我想请问各位大大高手帮我解决我的问题
* A" N! ^4 g. f! V" m7 V0 \0 c0 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。
9 y& S( _( W, @1 z" |6 c! ~那政府里又分为四种策略的人faithfuls ，trigger-punishments ，trigger-punishments ， mixeds + y& ~. p6 u2 R) m; j6 M7 Q5 s- D
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） 8 Z+ O$ g3 w, `3 \$ G
，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？$ Z, I8 P& H" h- \# R, Y2 h( _

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。
