Solving Three-objective Optimization Problems Using Evolutionary Dynamic Weighted Aggregation: Results and Analysis

ثبت نشده
چکیده

In this paper, evolutionary dynamic weighted aggregation methods are generalized to deal with three-objective optimization problems. Simulation results from two test problems show that the performance is quite satisfying. To take a closer look at the characteristics of the Pareto-optimal solutions in the parameter space, piecewise linear models are used to approximate the definition function in the parameter space that defines a Pareto-optimal front or the boundary of a Pareto-optimal surface. It is shown that such analyses are very helpful for recovering the true Pareto front.

Solving Three-Objective Optimization Problems Using Evolutionary Dynamic Weighted Aggregation: Results and Analysis

The main purposes of this paper is twofold. First, the evolutionary dynamic weighted aggregation (EDWA) [1] approaches are extended to the optimization of three-objective problems. Fig. 1 shows two example patterns for weight change. Through two three-objective test problems [2], the methods have shown to be effective. Theoretical analyses reveal that the success of the weighted aggregation bas...

An Improved Population Migration Algorithm for Solving Multi-Objective Optimization Problems

The population migration algorithm is a very effective evolutionary algorithm for solving single-objective optimization problems, but very few applications are available for solving multi-objective optimization problems (MOPs). The current study proposes an improved population migration algorithm for solving MOPs based on the vector evaluated method and the dynamic weighted aggregation. The loc...

Effectiveness of Weighted Aggregation of Objectives for Evolutionary Multiobjective Optimization: Methods, Analysis and Applications

Multiobjective optimization using the conventional weighted aggregation of the objectives method is known to have several drawbacks. In this paper, multiobjective optimization using the weighted aggregation method is approached with the help of evolutionary algorithms. It is shown through a number of test functions that a Pareto front can be achieved from one single run of evolutionary optimiza...
