Abstract
Ant colony algorithm is a widely used algorithm, it has its shadow in the power distribution, routing and other places. By studying the way of communication between ants, people discovered the way of using pheromone media to communicate indirectly, and developed the ant colony algorithm. Recently, Card-Cultivate Game to develop mobile games dominated the game all the rage, The levels of this type of game can be abstracted into undirected graphs, A lot of graph algorithms can be applied to this type of Card-Cultivate Game of mobile games. In this paper, ant colony algorithm is applied to Girls Frontline which is a mobile game, Ant colony algorithm is used to calculate the shortest distance from the enemy to the player's command post, let the enemy appear more intelligent, enhance the gaming experience.
