As a side note,a general form to assign ascending numbers (l to r, t to b) to patches is: set patch-id ( (pxcor + screen-edge-x) + (screen-size-x * ...
Here's another solution: Patches AND Turtles both have another important, and unique, identifier: The turtle, or patch, itself. You can store a reference to a...

Dear Netlogoers, I am struggling for days now to link groups of patches to a turtle! I am modeling land use where farmers (i.e. 28 turtles) own individual...

Dear Dr. Lilibeth Acosta-Michlik, I would think that the first thing you have to do is to assign the patches to the turtles. Do you have an idea about how the...
