The flower pollination algorithm is a new meta-heuristic algorithm that simulates the pollination behavior of flowers in nature. Aiming at the problem that the basic flower pollination algorithm is easy to fall into the local optimum and the later convergence speed is slow, the "adaptive-mutation catfish" flower pollination algorithm is proposed, Introduce the adaptive step size in the global pollination stage, introduce the mutation strategy and catfish effect in the local pollination stage, and use the classic test function to analyze the performance of the improved algorithm. The improved flower pollination algorithm is applied to the high breaking and comprehensive optimization design of the circuit breaker, the mathematical model of the high breaking and comprehensive optimization of the circuit breaker is constructed, and the optimal design method of the circuit breaker based on the flower pollination algorithm is given. The results show that the circuit breaker optimization design method based on flower pollination algorithm is feasible, and the improved flower pollination algorithm is effective.
