Metaheuristic means a High-level problem-independent algorithmic framework that is developed for the optimization algorithm. Metaheuristic algorithms find the best solution out of all possible solutions of an optimization. I discussed some Meta-heuristic algorithm like: Grey Wolf Optimization (GWO) Algorithm: GWO is a metaheuristic proposed by Mirjaliali Mohammad and Lewis, 2014. GWO is inspired by the social hierarchy and the hunting technique of Grey Wolves Bat Algorithm: The Bat algorithm is a metaheuristic algorithm for global optimization. It was inspired by the echolocation behavior of microbats. Cuckoo Search Algorithm: Cuckoo Search is a n ature-inspired algorithm , based on the brood reproductive strategy of cuckoo birds to increase their population. Meta-heuristic Algorithms
