“…EA is visualized to be very effective to deal with LFC problem due to its ability to treat nonlinear objective functions. Among the EA techniques, GA [24][25][26][27][28][29], PSO [30][31][32][33], Bacteria Foraging [34][35][36][37][38], Artificial Bee Colony [39], and Ant Colony Optimization [40] have attracted the attention in LFC controller design. Although these algorithms appear to be efficient for the design problem, they suffer from slow convergence problem in refined search stage, weak local search ability, which may lead them to get trapped in local minimum solution.…”
