说明：  多目标优化是在现实各个领域中都普遍存在的问题，每个目标不可能都同时达到最优，必须各有权重。但是，究竟要怎样分配这样的权重，这已经成为人们研究的热点问题。同时，根据生物进化论发展起来的遗传算法，也得到了人们的关注。将这两者结合起来，能够利用遗传算法的全局搜索能力，避免传统的多目标优化方法在寻优过程中陷入局部最优解，可以使解个体保持多样性。
(Multi objective optimization is a common problem in all fields of reality. Each objective can not be optimized at the same time, and each objective must have its own weight. However, how to allocate such weight has become a hot issue.)
