Netlogo entry-level programming help
Extend the NetLogo model Termites to include two types of wood chips which the termites gather independently into two separate piles. I have most of the code but I
cannot figure out how to get the termites to separate the chips into two different piles. They just seem to combine them. I would like you to work off of my code and
not rewrite the entire code.
