Gene-Similarity Normalization in a Genetic Algorithm for the Maximum k-Coverage Problem
Yourim Yoon, Yong-Hyuk Kim · Mathematics · 2020
The maximum k-coverage problem (MKCP) is a generalized covering problem which can be solved by genetic algorithms, but their operation is impeded by redundancy in the representation of solutions to MKCP. We introduce a normalization step for candidate solutions based on distance between genes which ensures that a standard crossover such as uniform and n-point crossovers produces a feasible solution and improves the solution quality. We present results from experiments in which this normalization was applied to a single crossover operation, and also results for example MKCPs.
