| Abstract: | This thesis analyses the principle and method which converts the solving problem of system of multivariate non-linear equations to the optimization problem of searching multivariate function extreme value, by using PSO＇s optimization ability in continuous space to find extreme points and the approximate solutions of the equations, and studies the special flow of the optimization algorithm, which shows the feasibility and effectivity through two examples, the results of these experiments present high effect and precision of the algorithm. |
