WebTo select two parental members for two offspring individuals creation, NSGA-II uses a binary tournament selection with two criteria -- a non-dominated sorting and a crowding distance. The tournament selection compares two members; if one member has a lower rank than the other, the member with lower rank is assigned into the mating pool. WebThe aim of this work is to find the optimal strategy for a forward–reverse logistics network by solving a multi-objective optimization model. Then, NSGA-II is applied. The NSGA-II method is mainly based on the genetic algorithm (GA). Generated populations are sorted by the non-dominated method [ 45, 46 ].
