Cuckoo search algorithm iteratively uses Lévy Flights random walk and Biased random walk to search for new individuals. In this paper,an enhanced cuckoo search was proposed,which employed elite opposition-based learning,simplex crossover and parameter control for the fraction probablity. The elite opposition-based learning strategy was used to avoid the new individuals being homogeneous in the Lévy Flights random walk. The simplex crossover strategy was utilized to reduce the inefficience of Biased random w...
