用于解决二次背包问题的多代理优化系统， 推荐研究学习一下-MAOS-QKP is a multiagent optimization system (MAOS) for solving the Quadratic Knapsack Problem (QKP).

设计模式中的代理模式，用C++实现，我自己做的一个例子，供新人参考-Design patterns in proxy mode, with C++, an example of my own doing, for the new reference

代理模式的java代码实现，通过几个类演示了代理模式，方便新手快速地学习和掌握。-Agency model java code, demonstrated by the several classes proxy mode to facilitate the novice to quickly learn and master.
