Abstract

The invention discloses a cuckoo search algorithm based on dynamic neighborhood learning, and the algorithm comprises the steps: firstly, modifying a Levy flight strategy, and enabling an individual optimal solution instead of an optimal solution obtained in the whole population so far to serve as a model for guiding a search behavior, so as to alleviate the premature convergence; Secondly, updating information of each individual in different dimensions by using different learning examples, and selecting the learning examples of each individual in each dimension from pre-defined neighborhoods;And finally, in order to further realize information exchange, setting a learning probability to control whether the individual learns to own experience or experience of neighbors of the individual.According to the invention, the optimization capability of the cuckoo search algorithm in processing the complex multi-mode problem can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of function optimization, in particular to a cuckoo search algorithm based on dynamic neighborhood learning. Background technique [0002] Currently, researchers have developed many evolutionary algorithms to solve different optimization problems. Among them, the cuckoo search (CS) algorithm is a newly proposed optimization method. In view of its advantages of less control parameters and easy implementation, the CS algorithm has received extensive attention and has been applied in many fields. [0003] The CS algorithm employs Levy flights and preference random walks to generate new candidate solutions, corresponding to exploration and development, respectively. However, in Levy flight, only using the occasional long-jump mechanism cannot guarantee that the algorithm can effectively explore the solution space, so its global search ability is weak; in addition, the search behavior of each individual is deter...
