我想请问各位大大高手帮我解决我的问题
" n, m; y8 E4 ]: a8 K: n; e) G8 r我先简述一下我所要做的模型，我的模型里，整体有两种人，政府与民众。
) f4 S8 N; u) V/ i. \那政府里又分为四种策略的人faithfuls ，trigger-punishments ，trigger-punishments ， mixeds * }( t+ w q, M( K$ r+ D8 t$ u
那政府要与民众互动，选择合作与不合作，政府合作和民众合作可得分(energy）
9 o5 ?1 O6 G- @; M" @1 N) ?，相对的不合作也有得分但当我要开始写规则的时候，却发现程式无法照我的意思去跑，想请问各位高手能帮我看看是哪里出问题了吗？

为什么不考虑用patches设定政府，假设政府不能够移动，民众可以通过用脚投票选择政府。这样也许可以解决你说的问题。
