如何让海龟在设定的半径内搜索具有设定条件的补丁

How do I make turtles search for patches with set conditions in a set radius

我正在尝试编写海龟搜索功能,其中:

如果社交性 >= 0.5 且局部斑块密度 < 目标密度

然后在半径 Moves_per_tick 中搜索密度与目标密度之差小于当前密度与目标密度之差的补丁。

如果存在则移动到那个补丁。 如果 none 存在则随机移动长度 moves_per_tick

但我对 NetLogo 语言还不够熟悉,无法做到这一点。我看过几个类似的问题,但其中 none 个问题让我离目标足够近了。

我目前正在处理这段代码,它在很多方面都有问题:

to start_search_personality
  let LD density
  let AT (Target_density * sociability)
  let C_D (AT - LD)

  if sociability >= 0.5 
  [
     ifelse C_D >= 0
      [
         let P any? one-of patches with (patches in-radius moves_per_tick with [density] > LD)
         if [density] of P > LD 
         [face p move-to p]]  
      [move-to patch-here]
  ]

密度由补丁拥有,定义为补丁中海龟的数量。 海龟具有社交能力,这是一个介于 0 和 1 之间的值。 目标密度是从别处输入的,是一个整数。

不要求任何人调试此代码,但至少让我知道我是否在正确的轨道上或建议我应该寻找的地方。谢谢!

这是我试图理解逻辑的最佳尝试。

to start_search_personality
  let density-here count turtles-here

  if sociability >= 0.5 and density-here < target-density
  [
     let p patches in-radius moves_per_tick
     ifelse any? p with [target-density < abs (density - target-density)] 
     [move-to one-of p with  [target-density < abs (density - target-density)]]
     [ ;;move in a random direction of length moves per tick
       set heading (random 360)
       fd moves_per_tick 
     ]     
  ]

使用上面的注释,我现在有了一个功能代码。如果您要为自己重新设计它,我建议您删除颜色更改(我只是用它来测试调用了每个函数)。 Target_density 固定在 运行 的开头,海龟拥有 s(固定在 0 和 1 之间),补丁拥有密度(在每个刻度上更新并定义为海龟在修补)。最后一个障碍是建立排名系统,因为此代码对高 target_densities

敏感
to check_personality
  move-to patch-here
  let N max-one-of neighbors [density]
   let ND max [density] of neighbors 
   let LD [density] of patch-here
   let AT (Target_density * s)
   let p patches in-radius moves_per_tick_baseline
   let diff_1 (AT - LD) < (AT - ND)
   let diff_2 (AT - LD) > (AT - ND)
   let diff_3 (AT - LD) = (AT - ND)

 ifelse s > 0.5

 [if LD < AT[ 

if diff_1 [ set color white
  ifelse density >= (0.90 * AT)
    [move-to patch-here]
    [ifelse any? p with [density > LD]
      [move-to one-of p with [density > LD]]
      [face N forward moves_per_tick_baseline]
    ]
   ] 

if diff_2[ set color gray
  move-to N
         ]

if diff_3
 [if ND < LD 
     [
     set color black 
     ifelse any? p with [density >= LD]
     [move-to one-of p with [density >= LD]]
     [face N forward moves_per_tick_baseline]
     ]

  if ND > LD 
     [move-to patch-here face N move-to N]]
  if ND = LD 
     [ifelse ND = 0 
       [set heading (random 360) forward moves_per_tick_baseline]
       [set heading (random 360) forward moves_per_tick_baseline]
     ]
 ]


 if LD >= AT [set color yellow set size 10]]
