Description

In a multi-objective optimization problem using NSGA-II, when the number of objective functions increases, it is unlikely to work a superior relation of solutions, so the search is stagnant and it is difficult to find a proper solution. In this paper, instead of performing crowding-distance sorting and preserving the individuals with the widest distance between individuals, we adopted a method of initializing the individuals belonging to the lowest rank and generating new individuals when selecting the individuals to be preserved in the next generation among the individuals classified into the lowest rank by fast non-dominated sorting. This can be expected to overcome the search that tends to be stagnant because the superior relationship does not work by the conventional method. As a result, when there are many objective functions, a solution closer to the Pareto optimal solution can be obtained compared to NSGA-II.
