说明：  通常，非线性整数规划是一个具有指数复杂度的NP问题，如果约束较为复杂，Matlab优化工具箱和一些优化软件比如lingo等，常常无法应用，即使能应用也不能给出一个较为令人满意的解。这时就需要针对问题设计专门的优化算法。下面举一个遗传算法应用于非线性整数规划的编程实例，供大家参考！
(Typically, nonlinear integer programming problem is NP exponential complexity, if the constraint is more complex, Matlab optimization toolbox and some optimization software such lingo like, often can not be applied, even if the applications are not able to give a more satisfactory solution. Then we need specialized for the problem of optimization algorithm. Here is an algorithm is applied to nonlinear integer programming genetic programming examples for your reference!)
