我想请问各位大大高手帮我解决我的问题
5 K$ ?! U2 _$ ^: Q: T. ]; a4 ?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。
, Q0 A( h9 @2 N, M9 d那政府里又分为四种策略的人faithfuls ，trigger-punishments ，trigger-punishments ， mixeds # O+ O" I+ }5 M7 o: U9 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） ) q4 I. p7 @5 F) G2 D. g- H
，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？' O W0 _) W, f; u- @
