This paper proposes a new metahaeuristic algorithm named particle swarm optimization and chaotic gravitational search algorithm (PSO-CGSA) for solving the combined economic and emission dispatch (CEED) problem. First. we determine the efficiency and effectiveness measures of the algorithm and compare it with other well-known algorithms.
