netlogo - Perspective based ranking? -


i have program each peer has own ranking system of other peers, best way implement netlogo?

normally, solve 2d list:
[[turtle 1, score], [turtle 2, score], ...]

but seems troubling in netlogo. code creating , modifying 2d list:

to test   clear-all   crt 10   ;create list of turtles   let agents-list [self] of turtles   ;create empty list, top level of twod list   let twod-list []    ;populate twod-list: [[turtle 0, 0], [turtle 1, 0], ...]   foreach agents-list [     set twod-list (lput (list ? 0) twod-list)   ]   show twod-list     repeat 5 [     ;change value in twod-list     let rand-index random (length twod-list) ;select random index     ;the next line makes huge headache, have select list @ top level replace, , select list @ lower level replace it.     ;this entire line of code adding 1 element     set twod-list (replace-item rand-index twod-list (replace-item 1 (item rand-index twod-list) (item 1 (item rand-index twod-list) + 1)))      show twod-list   ] end

what else can do? or there better way implement method?

if want model relations between agents, netlogo has perfect thing that: links!

having each turtle assign score other turtles can quite naturally expressed as:

directed-link-breed [ rankings ranking ] rankings-own [ score ] setup   clear-all   create-turtles 10   ask turtles [ create-rankings-to other turtles ]   ; increment 5 random rankings one:   ask n-of 5 rankings [ set score score + 1 ]   ; display rankings of each turtle:   ask turtles [ show [ (word end2 " " score) ] of my-out-rankings ] end

if don't want links show in view, can hide them with:

ask links [ set hidden? true ]
