基于视角的排名？

Question

我有一个程序，其中每个节点都有自己的其他节点排名系统，NetLogo 实现这个的最佳方法是什么？

通常，我会用二维列表来解决这个问题：
[[turtle 1, score], [turtle 2, score], ...]

但这在 NetLogo 中似乎很麻烦。这是我创建和修改二维列表的代码：

to test
  clear-all
  crt 10
  ;Create a list of turtles
  let agents-list [self] of turtles
  ;Create empty list, which will be the top level of the TwoD list
  let TwoD-list []

  ;Populate the 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 a value in the TwoD-list
    let rand-index random (length TwoD-list) ;select a random index
    ;The next line is what makes it a huge headache, basically you have to select a list at the top level to replace, and then select the list at the lower level to replace it.
    ;This entire line of code is just adding one to an 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

我还能做什么？或者有没有更好的方法来实现这个方法？

如果你想模拟代理之间的关系，NetLogo 有完美的选择：links!

让每只海龟给所有其他海龟打分可以很自然地表示为：

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

如果您不想让链接显示在视图中，您可以使用以下方法隐藏它们：

ask links [ set hidden? true ]
