A comprehensive review of cuckoo search: variants and hybrids (Q462665)

Summary: Cuckoo search (CS) is an efficient swarm-intelligence-based algorithm and significant developments have been made since its introduction in 2009 by \textit{X.-S. Yang} and \textit{S. Deb} [``Cuckoo search via Lévy flights'', in World congress on nature \& biologically inspired computing, NaBIC 2009, IEEE, 210--214 (2009)]. CS has many advantages due to its simplicity and efficiency in solving highly non-linear optimisation problems with real-world engineering applications. This paper provides a timely review of all the state-of-the-art developments in the last five years, including the discussions of theoretical background and research directions for future development of this powerful algorithm.
