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.

Genetic algorithms with heuristics rules to solve multi source single product flexible multistage logistics network problems

TL;DR: This research shows the proposed HR-GA has substantially reduced the elapsed time to obtain better acceptable solution to the multi source single product fMLN problem.

An Evolutionary Immune Approach for University Course Timetabling

Y. Awad, +2 more
TL;DR: An immune-inspired algorithm, namely the Clonal Selection Algorithm1 (CSA1) is formulating and testing its ability in solving the UCTP against the Genetic algorithm (GA), and an Immune-Genetic algorithm (IGA) was also created, which combines the crossover operator borrowed from the genetic algorithm with immune- inspired concepts.
