研究目的
To propose a predictive approach to the reproduction mechanism of new individuals for differential evolution (DE) algorithms by utilizing cumulative correlation information already existing in an evolutionary process.
研究成果
The DEEP framework enhances the reproduction mechanism of DE by incorporating the EP from CMA-ES, offering advantages of both DM and CM models. Experimental results demonstrate that DEEP algorithms perform better than original DEs and other state-of-the-art EAs on most test functions, especially as dimensionality increases.
研究不足
The study does not explicitly mention limitations, but potential areas for optimization could include further refinement of the self-adaptation mechanism and exploration of EP-dedicated mutation strategies.
1:Experimental Design and Method Selection:
The study adopts a key feature in the CM of a covariance matrix adaptation ES, the cumulatively learned evolution path (EP), to formulate a new evolutionary algorithm (EA) framework, termed DEEP.
2:Sample Selection and Data Sources:
Experiments are conducted on the CEC’13 test suites and two practical problems.
3:List of Experimental Equipment and Materials:
Not explicitly mentioned.
4:Experimental Procedures and Operational Workflow:
Two DEEP variants are developed and tested against original DEs and other relevant state-of-the-art EAs.
5:Data Analysis Methods:
Performance is evaluated based on mean absolute errors between the final best fitness and the theoretical best fitness, and the standard deviation over the given number of test runs.
