英文摘要：

Electromagnetism-like mechanism （EM） is a new population-based stochastic global optimization algorithm. A modified EM is proposed. According to the optimizing mechanism of EM, the computation equation for forces exerted on the charged particles was modified and a moving coefficient was introduced into the equation. The experimental results demonstrate that the modified algorithm accelerates the convergence speed and improves the precision of the solutions, especially in optimizing the functions with high dimensions, showing that the functions optimization with high dimensions can be solved by this algorithm well.
