Abstract: Shuffled Frog Leaping Algorithm (SFLA) is characterized by simplicity, few control parameters required, and easily be used. However, SFLA would easily trap into local optimum and have a low convergent precision when being used to address complex problems. As the traditional numerical optimization method, BFGS is of good local optimum ability. In order to improve the performance of SFLA, a new algorithm called SFLA based on BFGS is proposed, which combines the advantages of the methods of BFGS and SFLA, is put forward to solve systems of nonlinear functions. The experiment results show that the proposed algorithm is of the advantages of robustness, higher precision and faster speed by test of three systems of nonlinear functions. It is a good algorithm for solving systems of nonlinear functions.
