In this paper, the following work is done. The application of genetic algorithms in games is discussed, and based on reading relevant references, the design of the algorithm is explained in detail; the current situation of combining algorithms with games is analyzed; the novelty of combining algorithms with games is explained; and the paper concludes with a summary of the considerations and the scope of application of using genetic algorithms in games. The aim of the study is to reduce the cost of consultation and understanding for game makers and researchers, allowing them to focus on the specific application of genetic algorithms in games to make the AI of the game evolvable and intelligent to the level of the players.
