Abstract: A new Electromagnetism-like Mechanism (EM) algorithm was proposed in this paper in order to prevent data overflow and reduce the computation load. The formulas of the particle charge and the total force vector were improved. The lower bound of objective function and the formulas of the particle charge filtration were introduced. The standard test functions were tested and the new algorithm was compared with EM algorithm, which proved that the new algorithm converges faster. Furthermore, the numerical results show that the approach is efficient and valid.
