They have been used in function optimization, automatic control, robotics, and image processing, etc. In this article, a Matlab algorithm of the genetic algorithm to fit the given image with polygons is presented. Full codes are given for further use. http://www.iaees.org/publications/journals/selforganizology/articles/2021-8(1-2)/Matlab-method-to-fit-image-with-polygons-using-genetic-algorithm.pdf
