To address the issues of premature convergence and susceptibility to local optima in the traditional grey wolf optimization (GWO) algorithm, a multi - strategy integrated grey wolf algorithm is proposed. First, an improved Tent map is used to generate the initial grey wolf population, preventing the population from falling into local optima. Second, a nonlinear adaptive convergence factor is introduced to balance the algorithm's global exploration and local exploitation capabilities. Finally, the alpha wolf is endowed with an active search capability, enhancing its local search ability. Additionally, during the position update process, the algorithm retains the memory of the particles' historically best solutions. Comparative experiments on eight classical test functions for algorithm performance analysis demonstrate that the improved grey wolf algorithm significantly enhances solution accuracy and convergence. The application of the improved algorithm to intrusion detection classification shows a marked improvement in the detection accuracy of the model, meeting the high - precision and real - time requirements of intrusion detection in complex network environments.
