The electromagnetism-like method (EM) is a meta-heuristic algorithm utilizing an attraction-repulsion mechanism to move sample points (i.e., our solutions) towards the optimality. In general, the EM method has been initially used for solving continuous optimization problems and could not be applied on combinatorial optimization ones. This paper proposes a discrete binary version of the electromagnetism-like method (EM) for solving the combinatorial optimization problems. To show the efficiency of our proposed EM, we use it for solving the traveling salesman problem and compare our computational results with those reported in the literature. Finally we conclude that our method is capable of solving such well-known problems more efficiently than the previous works.
