Abstract EN
To improve the performance of the krill herd (KH) algorithm, in this paper, a Lévy-flight krill herd (LKH) algorithm is proposed for solving optimization tasks within limited computing time.
The improvement includes the addition of a new local Lévy-flight (LLF) operator during the process when updating krill in order to improve its efficiency and reliability coping with global numerical optimization problems.
The LLF operator encourages the exploitation and makes the krill individuals search the space carefully at the end of the search.
The elitism scheme is also applied to keep the best krill during the process when updating the krill.
Fourteen standard benchmark functions are used to verify the effects of these improvements and it is illustrated that, in most cases, the performance of this novel metaheuristic LKH method is superior to, or at least highly competitive with, the standard KH and other population-based optimization methods.
Especially, this new method can accelerate the global convergence speed to the true global optimum while preserving the main feature of the basic KH.
