Ouyang Aijia · Computer Engineering and Applications Journal · 2012
A Hybrid Population Migration Algorithm(HPMA),which combines the advantages of the two methods of Variable Metric Method(VMM)and Population Migration Algorithm(PMA),is proposed to solve systems of nonlinear functions,because there are some disadvantages of VMM is sensitive to the initial value,and PMA is inaccurate due to it easily fall into local optimal.The algorithm not only explores the global search performance of PMA but also exploits the local search ability of VMM.Experimental results show that HPMA not only has solved the all kinds of systems of nonlinear functions,but has high convergence rate and strong robustness,it is a good algorithm for solving systems of nonlinear functions.
