“…They provide a robust tool for solving multi-modal, discrete, stochastical-based and multi-objective non-linear constrained power system problems with a very high degree of computational efficiency. Examples include but not limited to genetic algorithm [18], particle swarm optimization [19], brainstorm optimization [20], moth-flame algorithm [21], adaptive cuckoo search algorithm [22], strength pareto multi-objective evolutionary algorithm [23], differential evolution [24], biogeography based optimization [25], gravitational search algorithm [26], fuzzy logic [27], artificial neural network [28], harmony search [29], Grey wolf optimization [30], hybrid fruit fly firefly optimization [31], bee colony algorithm [32], opposition krill herd algorithm [33], flower pollination algorithm [34] and firefly algorithm [35].…”
