Netlogo-计算相邻代理变量的差异

我想让每个代理询问他们的邻居一个海龟拥有的变量的价值,并根据它们的不同设置它们。

我知道如何在距离上做到这一点:

if (any? other turtles-here)
  [
    ask neighbors [ ;; ask 8 neighbors / neighbors4 for 4
      ;if (max-one-of turtles [distance myself]) <= 3
      ;[set opinion opinion - .1] ; no change in opinion
      ;if (distancexy point1-pxcor point1-pycor) > 20 and (distancexy point1-pxcor point1-pycor) <= 50
      ;[set point1-location "middle"]
      ;if (distancexy point1-pxcor point1-pycor) > 50
      ;[set point1-location "far"]
    ]

然而,我为实现价值交换而努力。我如何做到这一点?

这是我的MWE。

请注意,所讨论的代码部分是伪代码。

breed [ turtles ]
turtles-own [ variable ]

to setup
  clear-all
  create-turtles 100
  [
    set variable random-float 10
  ]
  reset-ticks
end

to communicate
  if (any? other turtles-here)
  [
    ask neighbors [
      pseudo-code: if difference of your variable and my variable is bigger then 3, than do nothing
      if differences less then 3, calculate the higher variable minus 0.1 and the lower variable plus 0.1
      if difference less then 2, calculate the higher variable minus 0.3 and the lower plus 0.3
      if difference less then 1, calculate the arithmetical mean
    ]
  ]

end

to go
  ask turtles [
    rt random 360
    fd 1
    communicate
  ]
  tick
end
