Abstract

Aim to solve the unconstrained optimization problemsaccording to the problems of the original Electromagnetism-like mechanism (EM) algorithm, such as large computation, low convergence rate, this paper proposes an improved EM algorithm after analyzing the function optimization principle of the original algorithm. By adopting the method for normalizing the objective function value, the power formula is simplified. By using an adaptive move operator, the particles have more chance to move into the other feasible regions. Experiments show that the improved algorithm has a better convergence result and higher efficiency.
