An Improved Lightning Attachment Procedure Optimization Algorithm for Constrained Optimization Problems

In order to improve the solution accuracy of the lightning attachment algorithm in dealing with constrained optimization problem, an improved constrained lightning attachment algorithm is proposed in this paper. Firstly, the parameter setting of the constraint processing technology was improved, and the constraint violation degree of all individuals in the population was added to further distinguish between feasible individuals and infeasible individuals; Secondly, several stages in the lightning attachment procedure optimization algorithm are improved, including the performance enhancement stage, the uplink leader stage, the downlink leader stage and so on. The improved constrained lightning attachment procedure optimization algorithm proposed in this paper is compared with the other three constrained optimization algorithms on the standard test function g01-g13. The results show that the algorithm proposed in this paper has certain advantages in solving precision.
