约束差异演化算法及其在机械结合面参数识别中的应用研究

constrained differential evolution algorithm (CDE) had been proposed. The CDE algorithm is based on the standard differential evolution algorithm, simulates the social phenomenon of "On the Fence", proposes the no strong-mined individual. Considering the characteristics of constrained optimization, we proposed the strategy of "Infeasible individual evolution". The proposed algorithm had 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 optimization model of parameter identification on machine joint surfaces, solved the problem by the CDE algorithm.
