Penalty Function Methods for Constrained Optimization with Genetic Algorithms

TLDR
These penalty-based methods for handling constraints in Genetic Algorithms are presented and discussed and their strengths and weaknesses are discussed.
Abstract
Genetic Algorithms are most directly suited to unconstrained optimization. Application of Genetic Algorithms to constrained optimization problems is often a challenging effort. Several methods have been proposed for handling constraints. The most common method in Genetic Algorithms to handle constraints is to use penalty functions. In this paper, we present these penalty-based methods and discuss their strengths and weaknesses.

Towards a mass customization in the fashion industry: An evolutionary decision aid model for apparel product platform design and optimization

TL;DR: In this paper, a two-stage platform-based design process is proposed to support apparel brands to implement mass customization (MC) strategies, where the first stage determines the characteristics of a scale-based platform (i.e., the number of product variants) based on the results of the anthropometric analysis of a large Italian female population sample, and the second stage, a novel and ad-hoc developed evolutionary-based decision aid model stretches and shrinks the resulting classes looking for the optimal trade-off based on anthropometric data between the demand of garments that fit well
