快速非支配排序算法，引进精英策略，保证某些优良的种群个体在进化过程中不会被丢弃，从而提高了优化结果的精度;采用拥挤度和拥挤度比较算子。(The fast non dominated sorting algorithm introduces the elite strategy to ensure that some excellent individual individuals will not be discarded during the evolution process, thus improving the precision of the optimization results; using the crowding degree and the crowding degree comparison operator.)
