Re: [netlogo-users] avoid duplicate turtle visits

[Wade Schuette]

You probably want to have the bizs own some variable like "visited",  which you can initialize to zero . ( or trust the system to do that but I prefer to be sure it gets done. ). 

Then instead of visiting a "biz" you want to only visit "bizs with [visited = 0]"

By the way, your code"  [move-to one-of [neighbors] of one-of bizs]"  moves prts to "neighbors" which the dictionary says are patches,  so you are asking your prt to move to a patch which is adjacent to the patch  that some biz is on,  not to a biz.

One solution might be to make your biz's patches, since they don't ever move, and recode your logic.

If you use patches, you don't need to invent a new variable, you could use pcolor to flag whether a patch has been visited or not,

which handles both the logical tracking and makes a visual display that is more informative.

I have two groups of turtles, prts (n=2) and bizs (n=10).  The mobile prts visit the immobile bizs.  My command to do this is:

ask one-of prts [move-to one-of [neighbors] of one-of bizs]

My question is how do I get the prts to only visit unvisited bizs?  More specifically, if prt1 visits bz1, I want neither prt1 nor prt2 to visit biz1 again.

Thanks, RB

Thanks for suggestions to address problems, one I identified and one not.  On the turtle vs. patch problem, have been trying to change turtle color but makes sense to change patch color.

Best, RB
