IntroductionThe evolutionary algorithm (EA) is defined as the set of goals used to solve any class of puzzle elements related to mathematical rules. Besides that, evolutionary algorithm is one of the problems to be solved to reduce or maximize a real function by analytically choosing the values ​​of real or integer variables from within an allowed set. In artificial intelligence, an EA is a subset of evolutionary computing, a general population-based meta-experimental operational algorithm. An EA uses the procedure inspired by biological progression, such as reproduction, mutation, recombination and selection. Application/Case StudyAt present, games such as Counter Strike Global Offensive and Life or Death 4 are always the most popular games in teenagers' lives. Most of the games that are popular in teenagers' lives nowadays are commonly developed using Genetic Algorithm (GA). However, using the games' core platform algorithm starting from mini-games and then high-range games, the interface and quality of the games transform quickly. For this case study, minigames are the main topic and one application is genetic algorithm and neural network. The complete topic of this case study is Genetic Algorithm and Neural Network for Minigames. Context/Review For this case study, the main points of consideration are physics simulation and character control. The investigation into these video game issues made use of some games suitable for exploring different aspects of the two main themes. The purpose of this case study is also to build the controllers, so the controller must be able to complete the explicit mission in the two games. The main focus of their case study is control… middle of the paper… spear game testing, balance before adjustment. Table 3 The fire mage skill set is more powerful than the ice mage skill set, as shown by the results. The researcher gradually made some changes to the settings of the three skills, and once a new setting was made, we performed the balance test to see whether the power of the two characters' skills was balanced or not. And after tweaking the settings and running the balance test a few times, we finally arrived at a setting such that the power of the two characters' abilities were balanced. We reduced the attack power of "Fireball" to Magic Attack Power × 401% + 414, increased the attack power of "Freezing Field" to Magic Attack Power × 296% + 320, and increased the maximum damage to 3 hits of the "Blizzard" ability. Table 4 below shows the skill balance after adjustment
