    Surrogate-assisted differential evolutionary algorithm with dynamic region exploration for expensive optimization problems

  • Original language description

    Currently, surrogate-assisted evolutionary algorithms (SAEAs) are widely used to solve computationally expensive optimization problems. However, in complex multimodal scenarios, there exists a notable likelihood that the algorithm might not converge to the optimal solution, highlighting the need to enhance the exploration capability of SAEAs. Therefore, exploring or developing different regions at different stages of the algorithm is crucial. This study designs a surrogate-assisted differential evolutionary algorithm with dynamic region exploration (DREDE) for expensive optimization problems. To filter out current suspected regions where better solutions might exist, anew criterion is proposed that combines the fitness level of a sample and its distance from the current optimal solution. By constructing surrogate models, DREDE dynamically performs global, local, and suspected region searches. A method for improving model accuracy by calculating the mean of selected individuals is introduced. These strategies synergistically enhance the performance of DREDE, which is comprehensively compared with several advanced SAEAs on seven benchmark functions with varying dimensions and was used in the reducer design problem. Simulation results showed that DREDE has a promising future in addressing costly practical issues.
