Abstract: In order to promote the landing of combat intention to combat action sequence, this paper briefly analyzes the shortcomings of current research on cooperative target assignment, and puts forward a problem model that comprehensively considers the factors of confrontation such as penetration probability. Based on the discrete differential evolution algorithm, the algorithm is improved from four aspects: population initialization, adaptive differential variation, random uniform crossover and constraint processing. Through the simulation experiment, the real-time performance and effectiveness of the improved differential evolution algorithm are verified.
