Problems solved by technology

This fuzzy membership function method gets rid of the dependence on experience to a certain extent, but its accuracy is poor, and it is not easy to choose a suitable fuzzy membership function.
[0007] Therefore, it is necessary to provide an effective and simple multi-objective fitness evaluation method to solve the fitness calculation problem of multi-objective optimization

Abstract

The invention discloses a fitness evaluation method for multi-objective optimization, which comprises the steps of selecting multiple optimization objectives; establishing a triangular comprehensive evaluation model; dividing the multiple optimization objectives into three types, and enabling the optimization objectives, which are divided into three types, to serve as input variables and be inputted into the triangular comprehensive evaluation model; and calculating a fitness function value of the optimization objectives, which are divided into three types, through the triangular comprehensiveevaluation model. The fitness evaluation method for multi-objective optimization realizes direct and effective calculation for the fitness function value of multi-objective optimization.

Description

technical field [0001] The invention relates to the field of multi-objective optimization, in particular to a multi-objective optimization fitness evaluation method. Background technique [0002] Optimization problem is one of the main problems in engineering practice and scientific research. Optimization problems are mainly divided into two categories: one is single-objective optimization problems with only one optimization objective, and the other is multi-objective optimization problems with two or more optimization objectives. Single-objective optimization does not consider other goals other than the optimization goal. In the process of single-objective optimization, it is often at the expense of other performance of the system, which is gradually abandoned by everyone. For multi-objective optimization problems, multiple optimization objectives can be considered in the optimization process to achieve the optimization of the overall performance of the system, so multi-ob...
