In order to address the disadvantages of the slime mold algorithm, such as limited adaptive ability and weak antistagnation capability, we propose an improved slime mold algorithm with multistrategy integration. Bernoulli chaos is used to generate the initial population, which enriches the population diversity, improves the optimization accuracy, and enhances the convergence speed of the algorithm. A dynamic nonlinear decreasing strategy is proposed to adjust the exploration range of slime mold individuals dynamically; this strategy coordinates and optimizes the global exploration and local exploitation capabilities of the algorithm. By combining the early warning mechanism of the sparrow search algorithm and refracted opposition-based learning, the foraging process of slime mold individuals is optimized, preventing the loss of high-quality individuals in the early stage and ensuring population diversity in the later stage, thereby improving the overall antistagnation capability of the algorithm. Comparative optimization experiments are conducted on benchmark functions and some CEC2017 test functions, demonstrating that the improved algorithm exhibits superior optimization accuracy and stability. Furthermore, the improved algorithm is used to optimize XGBoost parameters and is applied to transformer fault diagnosis, which further verifies the effectiveness of the improved strategy and the practicality of the algorithm in engineering applications.
