A Novel Self-Adaptive Harmony Search Algorithm

الملخص EN

The harmony search algorithm is a music-inspired optimization technology and has been successfully applied to diverse scientific and engineering problems.

However, like other metaheuristic algorithms, it still faces two difficulties: parameter setting and finding the optimal balance between diversity and intensity in searching.

This paper proposes a novel, self-adaptive search mechanism for optimization problems with continuous variables.

This new variant can automatically configure the evolutionary parameters in accordance with problem characteristics, such as the scale and the boundaries, and dynamically select evolutionary strategies in accordance with its search performance.

The new variant simplifies the parameter setting and efficiently solves all types of optimization problems with continuous variables.

Statistical test results show that this variant is considerably robust and outperforms the original harmony search (HS), improved harmony search (IHS), and other self-adaptive variants for large-scale optimization problems and constrained problems.
