英文摘要：

For solving the problems of nonlinear equations, an improved PRP algorithm is proposed based on the existing PRP algorithms. The proposed algorithm is proved to be globally convergent under suitable conditions. Numerical experiments show that this method is more competitive than the usual methods and is effective for solving nonlinear equations.
