Netlogo:限制代理可以建立的链接数 [英] Netlogo: limit the number of links an agent can make

问题描述

如果乌龟的var1值相等，我会联系它们(这很好).我想将链接数限制为三个.我在代码的链接部分(If count my-links < 3)之前添加了IF语句，但是它不起作用；代理商继续链接超过我设置的最大值.我阅读了另一个问题如何限制代理在模型中可以建立的链接数量，但这似乎并不能完全解决我在此所做的尝试.我在做什么错了?

I have turtles linking if they have an equal value for var1 (this works fine). I want to limit the number of links to just three. I added an IF statement before the linking part of the code (If count my-links < 3), but it does not work; the agents continue to link past the max value I set. I read the other question How to limit the number of links an agent can make in a model but that doesn't seem to quite do what I am attempting here. What am I doing wrong?

to communicate
  If count my-links < 3
  [
  ask other xagents in-radius 5 with [var1 = [var1] of myself]
  [create-links-with yagents in-radius 5 with [var1 = [var1] of myself]
    [
      set color white
      set thickness 0.1
    ]
  ]
  ]
end

推荐答案

在让乌龟创建新链接之前，请限制它们的链接数:

通过查看完整的模块，就像@JenB提到的那样，似乎没有条件限制目标乌龟用于建立链接的链接数量.

Limit number of links for the turtles before letting them create new ones:

By looking at your complete module, as @JenB mentioned that, it seems that there's no condition to limit number of links that the targeted turtle has for making a link.

这将是第一步:

to communicate
  If count my-links < 3
  [
  ask other xagents in-radius 5 with [(var1 = [var1] of myself) and (count my-links < 3)]
  [create-links-with yagents in-radius 5 with [(var1 = [var1] of myself) and (count my-links < 3)]
    [
      set color white
      set thickness 0.1
    ]
  ]
  ]
end

但是，如果没有这样的代理人怎么办? (半径为5，val1相同，链接数小于3)可能需要if语句.

But what if there's no agent like that? (in radius of 5, with the same val1 and links less than 3) Probably an if-statement is needed.

我还认为您需要在代码中使用one-of，以便在每个步骤中仅建立一个链接.

I also think you need to use one-of in your code to make only one link in each step.

您可以在communicate子过程的末尾使用此命令来杀死多余的链接.它具有随机删除链接的缺点，并且可能会从链接数量较少的海龟中删除链接，而不是可能也具有额外链接的链接.

You can have this at the end of your communicate sub-procedure to kill the extra links. It has a down-side of random removing links and also may remove the link from turtles with fewer link instead of the ones that may also have extra links.

ask turtles with [count my-links > LIMIT] [ if count my-links > LIMIT [ask n-of (count my-links - LIMIT) my-links [die]] ]
