“…In this period, many heuristics [37][38][39][40][41], exact algorithms [42][43][44][45][46][47], and IPs [6,42,44,[48][49][50][51][52][53][54] were proposed. Metaheuristics dominated the scene with neural networks [31,55,56], genetic algorithms , clustering strategies [83], ant colony optimization [76,[84][85][86][87][88][89], firefly algorithm [89], ant colony system [90,91], marketbased algorithms [92,93], imperialist competitive algorithm [94], tabu search [56], gravitational emulation local search algorithm [95], variable neighborhood search [96][97][98][99], bee colony optimization [100], invasive weed optimization [100], wolf pack search algorithm [101], discrete...…”
