Abstract: As an efficient swarm-intelligence-based algorithm, Cuckoo Search（CS） algorithm is inspired by the cuckoo breeding behavior in combination with the Lévy flight of some birds and fruit flies. Firstly, the principle of CS algorithm is introduced, and and it is compared with the current mainstream group intelligent algorithm to illustrate the effectiveness and deficiency of CS algorithm. Then the research achievements and application status of CS at home and abroad are introduced in detail, including binary CS, chaotic CS, discrete CS and other versions of CS, and applications in the fields of image processing, data mining, combinatorial optimization and other fields. Finally the further research directions of CS are proposed according to characteristics of CS algorithm and its application research results.
