摘要
En 中文
Cuckoo search (CS) has currently become one of the most favorable meta-heuristic algorithms (MHAs). In this article, a simple yet effective framework is proposed for CS algorithms to reinforce their performance, which contains two core mechanisms: computational resource allocation (CRA) and Gaussian sampling based re-initialization (GSR). The CRA is responsible for allocating more computational resources to promising individuals, thus promoting search efficiency and speeding up convergence, whilst the GSR is introduced to help the algorithm in maintaining population diversity. For testifying the effectiveness and generality of this framework (referred to as AR framework), it is embedded into nine well-established CS algorithms and extensive experiments are conducted on CEC 2013, CEC 2014, and CEC 2017 test suites. Experimental results indicate that the AR framework could bring a significant improvement on the performance of the classical CS as well as its variants, achieving an average efficient rate of 78.97%, 72.59%, and 86.21% on the three test suites, respectively. Besides, the comparisons between the classical CS, its AR framework version, and several other classical MHAs validate the effectiveness of the AR framework again. Additionally, the benefit of each mechanism (i.e., CRA and GSR) and their combination is also ascertained.
