Netlogo植絨型號代碼說明

Question

我正在調查netlogo的植絨模型。它具有以下奇怪的代碼。這段代碼做什麼數學？ 如果我在數學符號中看到這個，我會理解這一點。我想這是如何在netlogo中實現三角函數的？

to heading 
    turn-towards average-heading max-align-turn 
end 

to-report average-heading 
    let x-component sum [dx] of flock 
    let y-component sum [dy] of flock 
    ifelse x-component = 0 and y-component = 0 
    [ report heading ] 
    [ report atan x-component y-component ] 
end 

to turn-towards [new-heading max-turn] 
    turn-at-most (subtract-headings new-heading heading) max-turn 
end 

to turn-at-most [turn max-turn] 
    ifelse abs turn > max-turn 
    [ ifelse turn > 0 
     [ rt max-turn ] 
     [ lt max-turn ] ] 
    [ rt turn ] 
end 

Answer 1

to-report average-heading 
    let x-component sum [dx] of flock 
    let y-component sum [dy] of flock 
ifelse x-component = 0 and y-component = 0 
    [ report heading ] 
    [ report atan x-component y-component ] 
end 

dy and dy是龜標題所以我們所看到的是

程序報告 烏龜標題的正弦值的總和反正切，總和正弦和餘弦海龜的餘弦。

如果我們把標題和海龜的數量分開，我們最終會遇到很多問題，所以它顯然是這組角度的平均標題。
