Always follow the label on the Oxalic Acid. Oxalic acid is not a "toy" it should be handled with care.
Understand what you are getting into before mixing these pads.

Traveling Salesman with Specific Start and End Point
zhlédnutí 25KPřed 5 lety
Most videos on CZcams have not answered the questions that the students have needed. This video shows how to solve the Traveling Salesman problem from a specific start and end point. It also shows if certain stops need to be in order. Let me know how I can improve my videos. Comment below other questions I can answer in future videos.

    This won't get rid of mites entirely, it will slow down their reproduction rate to below that of the bees. But you will still need to treat later in the year, especially when the bee population crashes, and in late winter so they get a good start for spring.

      I've had pretty good luck with these pads alone. I have been at 0% while I've used these pads. However, it is something to monitor in case you need to take a different approach with your bees!

    Amazing Cody. What happens if there are 2 vehicle where both should at least reach 1 stadium once?

  • @jasonkepler898
    @jasonkepler898 Před 4 lety

    I tried this method with all of the baseball stadiums. I ran the solver till it told me it couldn't do better and it gave me a distance of 9,243 miles. But when I plotted the route it was obvious that that wasn't the shortest possible route. By manually doing the Travelling Salesman algorithm of going to the closest destination that hasn't been traveled to yet and then untwisting any loops that form, I got a distance of 7,481 miles. So the solver solution was 23.5% longer. But I'm not good enough with Excel to make it do my algorithm automatically, so it takes a long time to do it manually.

    gracias. una pregunta. ¿Cómo realizo la programación de las rutas cuando no se deben incluir todas las ciudades a visitar?. esto es, generar segmentos para rutear. por ejemplo. si hay 30 ciudades, pero yo solo necesito visitar 7 ciudades, ¿cómo se realiza? porque cuando se hace como lo planteas, solver busca las distancias mas cortas aún cuando la ciudad no está en la ruta que deseo, pero si en la tabla de distancias. Espero puedas ayudarme

    Pick up and deliver constraint for courier business. We have pickup A and C and delivery to B and D.. the courier can’only go to delivery point D if he has been to pickup point C. Can you put this as a formula to the solver?

    • @codyrae549
      @codyrae549 Před 4 lety

      Simply create an index number (much like our second constraint). Set the value to 1 if the index number of the last stop is greater than the previously desired stops

      @@MrDannySanders i have to pickup employees from their homes and drop off each employee in a different location. I have several cars, each car can have 4 employees in it. So A to B, C to D, E to F, G to H. Right now i'm solving it by picking up first and finding the shortest distance between pickup points(A,C,E,G) And then the shortest distance between delivery points(B,D,F,H). however, i could pickup A,C and then drop off B that would be great.

    Thanks for the nice explanation. Is there a way to include constraints which says we are not allowed to visit from city A to city B . In general we consider that all the cities are accessible from all other cities with a cost associated. But how do I let the solver know that certain routes between cities is not possible

      Just add a restriction, as he did. Or simply put an inmense ammout of distance in the data table from A to B (big M).

    Thanks for the constraint idea where you activate 1 for the starting point and activate 1 for a second stop.. and can probably continue adding 1s to keep the order specific @ certain stops.
