Center node: "a survey on dragonfly algorithm and its applications in engineering"
  Abstract: Dragonfly algorithm (DA) is one of the most recently developed#N#heuristic optimization algorithms by Mirjalili in 2016. It is now one of the most widely used algorithms. In some#N#cases, it outperforms the most popular algorithms. However, this algorithm is#N#not far from obstacles when it comes to complex optimization problems. In this#N#work, along with the strengths of the algorithm in solving real-world#N#optimization problems, the weakness of the algorithm to optimize complex#N#optimization problems is addressed. This survey presents a comprehensive#N#investigation of DA in the engineering area. First, an overview of the#N#algorithm is discussed. Additionally, the different variants of the algorithm#N#are addressed too. The combined versions of the DA with other techniques and#N#the modifications that have been done to make the algorithm work better are#N#shown. Besides, a survey on applications in engineering area that used DA is#N#offered. The algorithm is compared with some other metaheuristic algorithms to demonstrate#N#its ability to optimize problems comparing to the others. The results of the#N#algorithm from the works that utilized the DA in the literature and the results#N#of the benchmark functions showed that in comparison with some other algorithms#N#DA has an excellent performance, especially for small to medium problems.#N#Moreover, the bottlenecks of the algorithm and some future trends are#N#discussed. Authors conduct this research with the hope of offering beneficial#N#information about the DA to the researchers who want to study the algorithm and#N#utilize it to optimize engineering problems.
