【Abstract】 The method approximates the solution curve of the continuation method. Using the triangulation Ts,refining grid automatically,and homotopic mapping,the solution of systems of nonlinear equations can be approached with any given precision in finite steps of iterations. Several numerical examples and their analysis are given to show some advantages over the continuation method and the homotop algorithm.更多还原
