“…The development and the exploitation in metaheuristic approach are further exposed to improve the results while resolving the optimal reactive power dispatch problems (ORPD) such as; particle swarm optimization [11], harmony search algorithm [12], improved harmony search algorithm [13] gray wolf optimizer [14], cuckoo search algorithm [15], backtracking search algorithm [16], gravitational search algorithm [17], seeker optimization algorithm [18], gaussian bare-bones water cycle algorithm [19], colliding bodies optimization algorithm [20], chaotic krill herd algorithm [21], moth-flame algorithm [22], chaotic particle swarm optimization [23], bacterial colony chemotaxis algorithm [24], whale optimization algorithm [25], adaptive chaotic symbiotic organisms search algorithm [26], imperialist competitive algorithm [27], invasive weed optimization [28] and firefly algorithm [29]. Moreover, some other meta-heuristic approaches in support are discussed in [30][31][32][33][34][35].…”
