最优化实验外惩罚函数法，我们根据约束的特点，构造某种惩罚函数，然后加到目标函数中去，将约束问题求解转化为一系列的无约束问题。这种“惩罚策略”，对于无约束问题求解过程中的那些企图违反约束条件的目标点给予惩罚。(According to the characteristics of constraints, we construct some penalty function, and then add it to the objective function to transform the constraint problem into a series of unconstrained problems. This "punishment strategy" is a punishment for those who want to violate the constraint conditions in the process of solving unconstrained problems.)
