Giraffe puzzle next! 😁
Skeptic enters the chat
@@Mr.Puzzle come now, play fair!!😄
Way back in October 2018 I 3D printed my design of this puzzle which used the "dimples and holes" method of locating the pieces to force the 1 cell gap. This was after Carl Hoff posted the puzzle on the Twisty Puzzle forums. After trying on and off for weeks, Carl eventually gave me two hints, the placement of one corner piece and that the gap around pieces includes three 2x2 "rooms". With these hints I solved it in November 2019. According to Carl I was the first person to solve it without the help from a computer.
I love how, even 4 years later, Giraffe/5 is still a measure of impossible difficulty.
It's not impossible, it just takes too much time to make it worthwhile. Thanks though for the demo of the really cool software. Makes sense that a puzzle designed by a computer needed to be solved by another computer.
The existence (and demonstration) of the software was the most interesting part of the video.I am not specially into puzzle, but enjoy your contents.
Thanks!
Did you get what the software was called? Sounded like "bird tools" to my ear. Can't find it on google.
This was brilliant. I love watching you reason out how to solve the puzzles, and seeing that you needed software (along with a demonstration!) to get the one solution was just mind blowing. I also really appreciated the editing where you showed the software overlaid on the board as you placed each piece. Fantastic editing, and an amazing video. Thank you.
Thanks, glad to hear you like it.
I really enjoyed the video as well. Mr. Puzzle emailed me to let me know the video was up but I held off on watching it until I could watch it with my wife on our living room TV. He mentioned using Burr Tools and my wife's first comment was ""Oh that's so cheating" and that moment just made me grin from ear-to-ear. THANKS!!!
I solved this one by hand a while back, it took me quite a long time (and a hint by Carl himself) and my method was systematic elimination. I did get the hint that was given in Chris Ramsay's video and from there I tried to attach pieces to it. I tried tons of orientations of pieces adjacent to the hinted piece and systematically I could eliminate the options. Eventually it worked. So as far as I know and from what I have seen from this puzzle there is no other way to solve it other than systematically bruteforcing through the options. I think there also isn't any logical path, because this puzzle was created by chance after computer bruteforcing, so no logic implemented by the creator. I contacted Carl Hoff after the completion and we discussed a bunch of things about packing puzzles of this type. I think it is very interesting how quickly a packing puzzle becomes so incredibly difficult that it is almost necessary to use a computer to solve it in any reasonable amount of time.
I'm working through it systematically too. Haven't devoted enough time to come close to a solution. But I did notice some patterns.
The hint about the 3 2x2 rooms. If I make a 4th I know I need to backtrack somewhere because that's not correct.
There are some pieces that cannot be oriented together because they make a 3x2 room which isn't part of the solution.
Also, and idk if this is correct because I haven't found a solution yet... The 2 L shaped pieces with the belly on their back... I suspect must be oriented in a way so the belly on their backs faces inward to the puzzle. Otherwise those can be interchanged with each other if the belly faces the edges, and won't lead to a single solution.
Sigh... My week will be sad without Mr. puzzle... but I guess this gives me the motivation to sit down and finally finish the thing.
I used that fact to quickly eliminate cases. If you are going to attempt to solve it I can recommend keeping track of the things you have concluded can't work for sure. I didn't do this so I did the same thing way too many times and it could have easily been avoided by just keeping track of the attempted configurations
@@rubens_cube I have been keeping track. I have a folder on my phone of each piece beside the hint piece and different configurations it fits with the others that lead to near solutions so that I do not keep doing the same thing.
I also think there must be something to do with the math. The size of the grid compared to the pieces. Ex. There is only one 5x2 piece while the others are 4x3. But I'm not quite sure how to apply that configuration on the 11x11 grid to eliminate wasted space.
Also a pattern I noticed is that if pieces are arranged in a way that they make a straight edge somewhere in the puzzle that it's very difficult to create those 2x2 rooms and you're often left with bigger empty space. So they must be oriented in a staggered way so that others can slide in between kind of like a jigsaw.
Hello Ruben. Yes, I remember the conversation. I agree, it was the surprising difficulty of Untouchable 11 that got me interested in this type of packing puzzle. So I wanted to create as hard a puzzle as I could with as few pieces as possible. Hazmat Cargo to date is still my best product of that endeavor.
Absolutely fascinating and I’m very appreciative of you taking the time to demonstrate both the solution and the route to it. Thank you very much.
I think the one of the reasons why it's so hard is because it's counterintuitive in the sense that every edge is actually not occupied.
You did a great job with the visualization overlay on your demonstration of the solution. Great editing and video production. Keep up the good work.
love that this puzzle was finally solved!!! soo satisfying! AWESOME SOLVE!
I love the Overlay of the Real and Virtuell Board very nice done :-)
Glad to hear that!
Mr Puzzle you are just a genius, keep doing puzzles, it's amazing
Amazing. Really cool tool. Thanks for introduce it. Happy days!
That looked a Mr Puzzle personal difficulty rating of 3 at the start for sure... I'll will check out Mr Ramsey's attempt for giggles. I loved your graphic overlay at the end.👌
You could make the pieces twice as small and still "express" them as whole blocks. (Essentially, then you are not modelling the spherical holes as squares, but the gaps between each four of them.)
Does that make the solver faster? (Since it might not have to consider pieces in "odd" instead of "even" positions?) Or does it not work like that?
I did this and it only took 13.5 minutes to complete, finding the 1 solution.
Not sure if I understand it detail. Can you explain it again more in detail? Still leaning to work with it.
@@Mr.Puzzle Hi, mr. Puzzle. 😉
All your pieces consist of an integer number of square blocks of 2x2 tiles (except the frame). You could have defined them in terms of those blocks. Then the pieces become "smaller" concerning the number of grid positions they can occupy, simplifying the problem for the solver (I hope).
For example (warning: attempt at ascii art in non-monospaced font...), the piece with the cross shape
#
###
#
#
in your representation becomes
####
####
########
########
########
########
####
####
####
####
but you could also scale that down 2x to
##
####
####
##
##
Each tile (hashsymbol) then effectively doesn't coincide with a hole in the board, but fits precisely between the holes instead.
The 11x11 board became 24x24 in your case, or 26x26 including frame; in the smaller version it is only 12x12 big, or 14x14 including the frame.
BINGO!!!! Yes, it works EXACTLY like that. Mr. Puzzle made Burr Tools work much much harder than needed. Tahgtahv's 13.5 minutes is more in line with what I'd expect and keep in mind Burr Tools being more general than a 2D polyomino packing program isn't the more efficient 2D polyomino packing program out there.
@@Mr.Puzzle He is saying cut all your piece and board dimensions in half. Awww I see Dave Langers got here faster than I and spells it out in more detail.
Honestly the most surprising part was that this relatively simple puzzle (in terms of piece count) took 1.4 days for the software to brute-force the solution, when the extremely complex 3D skull puzzle took only a few hours. I guess the number of combinations was just exponentially higher because the pieces are all relatively the same size, while the 3D puzzle really only has a few ways that you can combine the largest pieces and then the smaller ones will have to be constrained to fit within that frame.
Very impressive and powerful software, either way.
I suspect that it's due to being a general purpose solver for a different kind of puzzle where directionality matters. I suspect that purpose built solver for flat packing puzzles would be significantly faster.
In the skull the possible. Combinations are limited. You cannot combine all pieces or quickly leave the solving shape. On the Hazmat puzzle you can place every piece everywhere. I think this is increasing the number configurations significantly
@@Mr.Puzzle Yeah, that's basically what I was thinking. There are relatively few ways to arrange the large pieces and still have them fit within the "frame" of the 3D shape it's supposed to make.
The 1.4 days is due to the piece definitions that Mr. Puzzle used. Tahgtahv (in another comment) used a different set of piece definitions and showed that Burr Tools is capable of solving this puzzle in 13.5 minutes. I have software that can solve it in 5 minutes and prove that the solution is unique in about 10 minutes.
@@Carl_Hoff I did wonder if that made a difference. I saw the comment that said he was trying that but he hadn't posted the results yet when I saw his comment.
That is so cool, awesome video! 👌
I feel like the physical gaps in the size of the pieces versus the board makes this puzzle ultra hard to conceptualize. As soon as I saw it, the logic part of my brain set off alarm bells saying, "run away"! Lol. What an amazing puzzle. It looks relatively simple seeing the solution, but I don't think I would have ever stumbled upon it.
I love that you love your son so much.
The Burr Tools software is pretty awesome! Thanks for showing that so we can give it a whirl for other uses!
One logical approach I found starts with 3 "corner pieces" in the sense that they waste less space than the other pieces when placed in a corner. The 4th corner piece is the one you pointed out that is not intuitive which also happens to be a hint Carl gave Chris. I replicated this puzzle out of paper but modified the shapes so they could touch like in your burr solver. Great minds think alike!
Well done on putting your hand up and admitting defeat.
Wow, everything about this video was brilliant. The software is astounding, I loved your editing at the end and your explanations were spot on.
Really different video from you but fantastic all the same.
The giraffe puzzle was crazy hard. but I still believe the telephone puzzle that Chris Ramsey did was way beyond extreme
THANK YOU!
Considering that I’ve tried to pester you for a year with the hazmat puzzle, I’m glad to finally see it solved 😃
Interesting to see and understand “how”
So close to 1 mill subs! Great job
Thanks!
@@Mr.Puzzle I have been subbed for at least 4+ years and you definitely got puzzles 😄👍 I remember this one time you did this see through coin puzzle I think it was circular (the safe) and I think I mentioned that you could almost see a face reveal you can Ramsay are really good puzzle masters for sure
whoa, I can't believe it's actually approaching the giraffe in difficulty level
Never!
Okay but now I’m super intrigued and don’t want the solution ruined if it beat Mr Puzzle!
Impressive!!! ❤️
I’m always a fan of puzzles that have multiple solutions. I understand the point of using a computer to aid in the design of a puzzle, but I think it can get out of hand and quickly generate puzzles which can only be solved by a computer.
they're not just hexominoes, they're all cube unfoldings
I think you are thinking of the Untouchable 11 puzzle. That is not true for the 9 pieces in this puzzle.
@@Carl_Hoff I was going off how they look, it seems only one of the pieces isn't a cube unfolding, all the rest are though
@@AB-Prince That is correct.
I had to go through your old videos to see this giraffe puzzle and found it in the Level 5 playlist. Definitely harder than this one.
I saw the giraffe video when it was released so I understood the reference. But honestly I had no idea that giraffe had taken on a life of its own since that video. Reading though these comments I see Mr. Puzzle even using a small image of a giraffe in his comments, so cute. I've been wondering how he was doing that and I just now figured it out.🦒I agree no other puzzle will ever be able to dethrone🦒and that is as it should be.
I'm definitely looking up that Burr Tools software! Looks fun for not only solving but coming up with new puzzles!
That's what it is made for. If you create something, let me know.
Haha I remember the diabolical, unsolvable giraffe. Wasn't that one of your most viewed vids?
Yes, Giraffe puzzle is just a smidgen harder than this one I believe.
I really enjoyed watching this, seeing the Burr computer program is quite amazing. Thank you for sharing!
The frustration is clearly shown on this one. It looks like when you finally defeat a hard boss, but this time it is not the puzzle, but yourself. Thanks for the explanation and if the computer took at least a day to come with a viable solution, yeah, mission accomplished by the puzzle maker. I think this is a first!
I used the program recently to help me to assemble the arjeu CT 666. Sometimes, it is necessary "think out the box" to solve a puzzle. Good job figured out how to convert it to computer :)
I think the trick here is exactly in the gaps between the pieces which throw you off in terms of lining up gaps
Those gaps along the edges make it extra difficult. Because my initial plan would be to work it like a regular puzzle and try to build the edges. But there is no true edge because of the gaps.
It is possible to turn this puzzle into a normal packing puzzle that fills a board with no gaps. Are you familiar with the notion that the dual of the triangular grid in the hexagonal grid? If so, ask yourself what the dual of this square grid is. In short think of the puzzle as a packing of the vertices and not a packing of the squares. The 9 hexominoes become 14-ominoes as they each contain 14 vertices. The 11x11 board becomes a 12x12 board when you count all the vertices on the edges. 12^2 - 9*14 = 18 So you need 18 monominoes to complete the puzzle. With this picture, there are no voids and the solution is still exactly the same. However the 9 piece puzzle becomes a 27 piece puzzle. Just save the monominoes for last as they will always fit in the empty spaces and you can still think of it as a 9 piece puzzle.
Definitely a level below "The Giraffe". A computer would never solve that one. It was pure luck that you found a genius that could solve it. 👍😄
Agreed. Even 'deep thought' wouldn't have cracked the giraffe. And that solved the ultimate answer......
42 is definitely not the ultimate answer. We all know what it really is... 🦒
😆😆
That looks hard but nothing beats level giraffe
I often revisit that video and still come away none the wiser of the solution!
I was kind of expecting all of the little nuclear/biohazard symbols to face the same direction once the puzzle was solved. Perhaps this could be used to create another variation on this style of puzzle with a slightly easier difficulty level.
It could. But I intentionally did NOT do that. And yes, I was aware of that possibility.
Thats so cool but literally mind-boggling very fascinating ill never be that smart
Blimey that's one puzzle I won't be looking out for
I am curious about the giraffe, have you ever solved it?
He had help!
Not myself.
As a programmer, I appreciate the meticulous modeling and approach to solving. Puzzle solving is problem solving, and thinking outside of the box is always intersting. Isn't this model able as a bounded knapsack style problem and solved much faster with dynamic programming than a day and a half of computation time?
Could you share a link to download that software, please? I would love to give it a try. Thanks in advance!
Just Google Burrtools
@@Mr.Puzzle Thanks a million! My English is bad and I was googling Bird Tools 😅
Giraffe -1 = this puzzle.
Happy new year
Open Window. Throw as far as I possibly could. Close window. Close blind. Don't look outside ever again.
😂😂
Is this puzzle available anymore, anywhere, for purchase?
In the future, puzzles will be randomly generated. -- vegetales
Outstanding puzzle you are PUZZLE MASTER!! May I have the name or website for the program that you used
Please Google Burrtools
I think that I may be one of the few that think that using programs like this to solve a puzzle are just a different way to arrive at the solve. In order to use that program, you need to understand the puzzle in every part. If any part of your logic is off, you will get an incorrect solve. All that you are using the computer for is to run through the permutations of finding g the solution, which essentially is just Time.
Nothing will be as difficult as the giraffe
wow cool
Oh no... Did you solve this... My goodness I cannot watch this yet. I haven't solved mine! I may never watch this video 😭
You may notice there is no spoiler warning in this video. And then he proceeds to calculate the solution with a computer.
How would you approach this difficult puzzle?
I like this puzzle looks easy but is hard👌
Hammer. Big hammer. I learned that from Jeremy Clarkson.
I'd copy you!
@@casperthefriendlycookingapple Yeah, I would just watch the video. LOL.
Process of elimination, start with a piece and try permutations around that ..... although if it took software a day and a half to solve.. ... 🤔
Love the thumbnail
Agreed. It is very nice. Is there any way to see that image at full resolution?
Have you tried using burrtools to solve the giraffe?
Waiting for quantum computers to running the calculation. Would probably reduce it to a few million years, which would be awesome!
The first thing i notice, this grid look to be a 11x11 square made of circle and the pieces have half spherical shape that fit in.
8 pieces look to be 3x4
1 piece look to be 2x5
The Giraffe.. Not only it has one single solution but also only one person who can solve it. No computer, no program no one ever will be able to solve it. 🦒 ♥️
True!
I do that stuff in my head, that display stuff I solved my first interlock puzzle age 6
a puzzle that mr. Puzzle couldn’t solve? am I in bizzarro world? I refuse to believe!
I'm on cloud nine. I made a puzzle and wanted to see who was the better puzzle solver, Mr. Puzzle or Chris Ramsay. I never expected this.
@@Carl_Hoff Ramsay does have a fantastic cinematographer on the team and rather fun content, but when it comes to logical problem solving he can’t hold a candle to the real OG, mr. Puzzle.
Btw, fantastic work on the puzzle, mr. Hoff!
That Giraffe puzzle was incredibly hard, (lol) so I don't think you're going to be able to top that one, ha, ha.
I agree, impossible....
I Gave this puzzle some thought and I can't see any any sort of logical solution so you'll have to just use trial and error to solve this puzzle. The best way to employ trial and error is to to use a method of elimination to come to the solution as follows:
1. Start by dividing the puzzle space into three rows (Top, middle, and bottom) as the actual solution has the pieces in three rows.
2. Starting with the top row, place place any three pieces that fit into .
3. Move to the middle row and place another three pieces that fit into it.
4. Move to the bottom row and try and fit the three remaining pieces into it.
5. Assuming you don't get amazingly lucky in your first attempt, thne bottom three pieces won't fit so you should remove them and try and see if you can rearrange the middle row then retry the bottom three pieces if the middle row can be prearranged.
6. Try a different combinations of pieces in the middle row and then the bottom row until you have tired every combination of the last six pieces. Always check yo see if the middle row pieces can be rearranged then follow by the bottom row if possible. Never touch the top row of pieces until you have tried every combination of the muddle and bottom rows of the six remaining pieces.
7. If you don't get lucky up to this point, then try rearranging the top row if possible and if so then repeat steps 3 to 6. If not then try swapping a pieces from the remaining six pieces and trying steps 3 to 7 again.
8. Keep swapping pieces on the top row and repeating steps 3 to 7 again until all combination of pieces has been tried in all possible orders on the top row. Eventually you will hot on the solution. It may take a very long time but you will eventually get there.
The hard part is tracking what you already tried to not repeat it over and over again.
Great!! What is the name of the software please?
The Giraffe is The Puzzle of All Time 😁👍
Thank you for solving it unlike some other youtubers that left us hanging 🥴
Just watched Chris Ramsey's buddy solve this puzzle but at least you got it 2nd.
First check, then comment..
Is this one of the few puzzles that required a computer for you?
So we can estimate the difficulty level with the formula:
(5 + giraffe)/2, plus or minus of couple of bananas.
You can't add, substact, multiply or divide anything with the giraffe. Giraffe is giraffe, anything else can be neglected...
🦒
Could the colors of the symbols have a pattern? Hard to tell from the video. Interesting software tho!
The colors were picked at random so no there isn't (or shouldn't be) a hint there.
What's the name of that tool? Virtool?
Burrtools
@@Mr.Puzzle Thank you!
I think I have found a logical way of approaching this puzzle, I'm currently drawing this out because outside of visual representation I won't be able to explain this thoroughly. Give me a about a hour and I'll edit this comment with a attachment link.
Do you think the clue is that the gaps between spell “hazmat”?
These types of packing puzzles are a variation on the famous mathematical Bin Packing Problem. ( en.wikipedia.org/wiki/Bin_packing_problem ) The Bin Packing Problem, along with other problems like the Traveling Salesman Problem or "TSP" ( en.wikipedia.org/wiki/Travelling_salesman_problem ) are both known in computational theory as "NP-complete." ( en.wikipedia.org/wiki/NP-completeness ) ( From Wikipedia) a problem is NP-complete when:
1. it is a problem for which the correctness of each solution can be verified quickly and a brute-force search algorithm can find a solution by trying all possible solutions.
2. the problem can be used to simulate every other problem for which we can verify quickly that a solution is correct. In this sense, NP-complete problems are the hardest of the problems to which solutions can be verified quickly. If we could find solutions of some NP-complete problem quickly, we could quickly find the solutions of every other problem to which a given solution can be easily verified.
Although a solution to an NP-complete problem can be verified "quickly", there is no known way to find a solution quickly. That is, the time required to solve the problem using any currently known algorithm increases rapidly as the size of the problem grows. As a consequence, determining whether it is possible to solve these problems quickly, called the P versus NP problem, is one of the fundamental unsolved problems in computer science today.
If you can fine a general way to find "quickly" find a solution to a Bin Packing Problem other than brute force, then you have found a general way to "quickly" find solutions to ALL NP-COMPLETE problems. You will win some very prestigious mathematical prize, probably a Nobel prize, and lots of money. You will have found the answer to the P vs. NP question which is one of the top five, maybe top three (?), open questions in physics and math. Right up there with, "Does a grand unified theory of the universe exist?"
If you think this is difficult, he can VERY EASILY make it exponentially more difficult just by adding one more piece. By the way, finding a bitcoin is an NP-Complete problem, and they can easily make it exponentially more difficult just by adding another bit to the number being searched for.
I would say you solved it. I mean, it was created using a computer, I think it is fair game to use one to solve a maximally-numeric puzzle like this. Cheers!
His giraffe specialist could have solved this in half a day.
Where did you get this puzzle. i want to buy it.
This copy was made by Carl Hoff himself and send to me as a gift.
See the link in the video description. If you want one with a wooden board as seen in the video, email me. You can find my email address at the end of the paper, also linked to in the video description.
Is this puzzle for sale, the pieces with the radiation trefoil look cool, I've only managed to find the untouchable 11 on shapeways. I'd definitely be interested in buying it. Thanks Carl for a great puzzle.
See video description
Thanks Mr Puzzle, but the one for sale in that website isn't the one with the funky radiation trefoil symbols on them, they look way cooler, is that one for sake too, or was it a custom design ? 😕☹
@@jeffcarr392 I plan on making more but at the moment I do not have any more of the ones with the wooden boards available. If you email me I will add you to the wait list and notify you when they are available. My email address is at the end of the paper posted at the G4G link in the video description.
I would first try to solve this puzzle without the wooden plate, for example on the table. So, I can move and rearrange the pieces more easily.
I would eliminate the impossible combinations. The length of the plate is eleven units. So, you can't have a combination of 3 pieces with 10 squares horizontally or vertically, for example.
Then I start solving the puzzle with trial and error.
Interesting idea
In my opinion it's more satisfying if you solved the puzzle without the programme, even though it would take more than one year to solve it.
I wonder why the pieces are layed down with these "semi-spheres" on the upside? There are holes in the board, so I imagined to lay the pieces with these colored spheres into to holes, but the holes seem to be not big enough?
Funny part I don't think you all noticed no Circle on the board is complete when it's solved pay attention that would have been easy to figure out right
Giraffe lol 😆 April 1st
Are you familiar with the Eternity and Eternity II puzzles?
Yes.
I have the Eternity II here but still boxed. According to what I know it was not solved yet by anyone.
@@Mr.Puzzle Yes, only the Eternity was solved I believe. These puzzles are NP-problem puzzles while others "similar" puzzles can be solved using e.g. Dijkstra's algorithm, "Rush Hour" being a prominent example, one of the best puzzles of all time IMHO.
How do you tell Burr Tools that it can have holes in the final result?
It found it by itself. If you are not sure if there are holes you use the voxels with black sides. They are representing areas that can be either filled or empty in the final configuration.
Очень простой пазл, две ключевые фигуры слева в центре две, остальное просто по краям выставляется
In the solution similar colors are grouped together. Not sure knowing that would make it solvable.
First of all I don’t like a puzzle with one solution because tbh I kinda always solve those types of puzzles because I just an eye for one solution and the ones with like a lot are harder for me because I don’t know if what I do is a solution or not
Karen Puzzles could solve it. She’s amazing.
I discovered her after I was already familiar with Chris Ramsay and Mr. Puzzle. I do plan to reach out to her and offer her a copy the next time I have some sets with wooden boards made. I agree... I think she has got a good chance. Only concern is she may come to hate me for sending it to her.
@@Carl_Hoff ahahahaha! That’s great news! She has an amazing way of seeing how pieces fit together. She does these solid color 1000 piece jigsaw puzzles that would drive a normal person bananas.
The reason the puzzle is so difficult is that it has only 1 solution. Your brain has no way of remember every combination you have tried, if you also think that the one part could not be in the corner and waste space then you just never tried the puzzle with it in the corner and even if you did you might not have got the solution. They did some scientific testing with puzzles like this and they found young children are more likely to solve this puzzle faster than an adult.
Yes and no... The fact that the puzzle only has 1 solution (and you are given that info) can also be used to prune the search space as you can use it to rule out configurations where any two pieces could be swapped without affecting the other pieces. I can assure you this is one thing Burr Tools isn't doing so the search space a human would need to search is significantly smaller then that searched by all the polyomino packing programs that I am aware of.
Is it just me or does it look like the solution was sort of color coded? Looked like all the reds in the upper left, blues in upper right and greens below.
I think what makes the puzzle hard is that we usually define ‘packing puzzle’ as one that needs the corners filled with no gaps. it’s not entirely intuitive to realize that there can be gaps, and especially when it’s ‘radioactive cargo’. if you thought of this one where low gravity is involved maybe the solution would make more sense….but then, who is thinking of low gravity when it comes transporting hazards? eh. I’m glad the burr program was able to be of use.
also, I have been playing Professor Layton and the Unwound Future: there is a gravity related packing puzzle in the game, I think some folk might know what I’m referring to….
Mr. P, this puzzle solution was almost painful for my brain. I like to think that I'm not a dumb person, but I've always been aware that my mental gifts reside more in the realms of words, visual arts, music...all the instinctual, emotional, artsy stuff. I've enjoyed many of your videos because you're intellectual gift is much more mathematical and logically analytical than mine. I've enjoyed vicariously, through your fun (but smart) approach to seemingly baffling puzzles, pretending that I could also, possibly, understand your solutions. But you lost me this time. This, for me, was intellectually impenetrable. Time for a glass of wine and some Chopin!
Next time! 😁
You should have called in the pro on that one. I'm just saying, here solved the giraffe so easily this one would have been nothing to him. 😃
You are probably right.
It ca be solved manually, since the number of piezes is not much, the aproach to start is to count and the understand how much gap is not used, then arrange them out of the container and after that refine the shape minimizing the area used.
The number of steps of try and error is big but not imposible to do in a few days ... but it is needed to be very methodic to not loose what has been tried.
If that is done with a computer that is technically not solved by human, also not if that human made the software, hardware, etc.; that would be a human making a tool that such tool solves it.
This kind of puzzles can also be solved with brute force attacks, but that is not the point for the puzzles, it is to discoved a way to solve it.
But in the end it is up to every one how to consoder it solved by human.
Trying methodically all steps will definitely not take a few days. This is what the computer did and it took 1,5.days. The point is, since this puzzle was designed by a computer it is just try and error.
@@Mr.Puzzle Not sure about how the program places the pieces, but with one piece putted there is no sense to place the next not touching the first (that would cause repeated positioning tests).
Since time taken by the program i am thinking the program do not uses math space positioning and try every piece on every place,msub-optimal very sub-optimal.
Once one or more pieces are put there is no need to test any other piece on a position not touching the pieces that are put, the objective is fill a gap.
Hope my bad english is enough good to be understand.
