Abstract: In this paper, an incorporated constrained differential evolution algorithm based on Invasive Weed Optimisation (IWCDE) had been proposed. The IWCDE algorithm is based on the standard differential evolution algorithm and incorporates the Invasive Weed Optimisation Algorithm. The IWCDE algorithm proposed the new mutation strategy and the strategy of 'Infeasible individual evolution'. The proposed algorithm was compared with several other evolutionary algorithms, the results showed that the proposed algorithm could overcome the premature convergence efficiently and had better global convergence and robustness. Finally, the paper established the optimisation model of parameter identification on machine joint surfaces, solved the problem by the IWCDE algorithm.
Keywords: constrained optimisation; differential evolution algorithm; invasive weed optimisation; infeasible individual evolution.
