我想请问各位大大高手帮我解决我的问题
% [7 Z6 u* E4 E2 d' E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。 2 Y* J* ?1 G& I
那政府里又分为四种策略的人faithfuls ，trigger-punishments ，trigger-punishments ， mixeds
* y; N& `- ~' ]" y0 ?+ 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）
7 q- l r6 F) }2 L# A! U，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。
