A multiobjective optimization method aims to find the solutions that are as close as possible to the Pareto-optimal front. Sign in to download full-size image Fig. 10.4. Design space, objective space, and Pareto
SOLUTION: In the field of multi-objective optimization using evolutionary algorithms, conventionally different objectives are aggregated and combined into one objective function by using a fixed weight when more than one objective needs to be optimized. With such a weighted aggregation, only one ...
相比于单目标优化问题,多目标优化问题[1]是系统性地同时优化一系列目标函数的过程,也被称为矢量优化(vector optimization)。 前一篇文章介绍了多目标优化问题的基本形式和基于性质的帕累托最优解确定,这篇文章将继续根据文献[1]总结多目标优化问题的求解方法,并最后给出一个具体例子详细说明求解多目标优化问题的过程...
The method for finding the global optimum of any function (may not be unique) is referred to as Global Optimization. In general, the global minimum of a single-objective problem is presented in Definition 2 [1]: Definition 2 Single-Objective Global Minimum Optimization Given a function f:Ω...
