Short summary
To enhance the convergence speed, accuracy, and high-dimensional constrained optimization problem-solving capability of the traditional gray wolf optimization algorithm, an improved gray wolf optimization algorithm is proposed by integrating an optimal individual memory strategy, a position update strategy with differential variance, and a discrete crossover factor. Experimental results show that the improved algorithm outperforms other comparative ones.
