Dragonfly algorithm in 2020: review

Swarm Intelligence is the meta-heuristic algorithm that is inspired by the natural behavior of some groups of animals (like dragonfly, ants, ducks, etc.) striving for their life existence. One of them is Dragonfly Algorithm. Dragonfly Algorithm has been used to solve real-world nonlinear problems in engineering. In this paper, we reviewed Dragonfly Algorithm implementation in 2020. We collected papers that related to Dragonfly Algorithm in 2020, then we discussed it based on the subtopic that we stated. From our observation, we got the insight that this algorithm was excellent to implement optimization in some networks or electricals problems. Mostly, to get the best result, Dragonfly Algorithm must be hybridized with the other algorithm.
