I am trying to improve my understanding of lists in NetLogo. Shortly, I am adding and picking (and removing) items from lists. Each turtle has its own list. Each list should contain items in a chronological order, from the most recent to the oldest. Once a turtle chooses an item, the neighbours have this item on the top of their lists (same for the turtle that chooses the item). What I tried to do is:
rnd:weighted-one-of-list mylist [ [ii] -> ii ] ; pick one of the most recent items already in the list
set mylist lput old_item mylist print "Old item" ; add items to the list
using the extension as JenB suggested in a previous post.
Condition to use pick an item from a list (old item) is that mylist is not empty (if empty? mylist).
My question is if it is correct to pick an item using the extension in that way as I did.
UPDATE: The list is made up in the following way:
I decide to create a new item, item 4 with quality 2 (quality is a parameter in [0,5]).
I add this item in my list (item 4, item3, item2, item1) - from the most recent to the oldest - with quality item4 2, item3 1, item2 2, item1 5, respectively, and in neighbours' lists: neighbour1, for example, would have list (item4, item 11, item 10,..) with quality 2, 3, 1, respectively.
What I would expect is to pick an item from the list based on the quality parameter. This would mean that I would pick item1 from mylist. My neighbours would pick item11 as it has quality equal to 3, i.e. the highest in its group.
Thank you for your help.
