罚函数方法是求解约束（极小）优化问题的一类较好的算法。其基本思想：根据约束的特点构造某种惩罚函数，并把惩罚函数添加到目标函数上去，从而得到一个增广目标函数，使约束优化问题的求解转化为一系列无约束极小优化问题的求解。-Penalty function method for solving constrained (minimum) optimization problem of a class of better algorithms. The basic idea: In accordance

优化方法：本案例属于有约束问题，利用外罚函数法进行求解。-Optimization Method: This case belongs to the constrained problem is solved outside the penalty function method use. Which solved using c++ programming.
