“…Evolutionary algorithms have been extensively used to solve the GEP optimization problem, ie, GA, [29][30][31][37][38][39][40] particle swarm optimization, 24,32,40-43 differential evolution, 39,40,44,45 ant colony optimization, 39,46 and evolution strategies (ES). 39,40 Moreover, some hybrid approaches combining GA with simulated annealing, 47 GA with generalized Benders decomposition, 48 and GA with dynamic programming 49 have been proposed.…”
