The paper presents a novel variant of the Grey Wolf Optimizer (GWO), termed Enhanced Balance Grey Wolf Optimizer (EBGWO), which addresses two key limitations of the original GWO algorithm:
Lack of an elite inheritance mechanism: The original GWO algorithm fails to inherit elite positions from the previous iteration, potentially leading to suboptimal solutions. The proposed EBGWO introduces an elite inheritance mechanism that selectively employs elite individuals from the previous positions to guide the updating of positions in the next iteration.
Insufficient exploration capability: The position updating mechanism in GWO relies on the center positions of three candidate wolves, which is a locally greedy optimization strategy that favors exploitation over exploration. This can lead to inaccurate calculation of the optimal solution and trapping the algorithm in local optima. EBGWO introduces a balance search mechanism that dynamically adjusts between global and local search to enhance exploration capability.
The performance of EBGWO is evaluated using benchmark functions and real-world engineering design optimization problems. The results demonstrate that EBGWO outperforms other meta-heuristic algorithms in terms of accuracy, convergence speed, and the ability to avoid local optima. The balance between exploration and exploitation is also improved compared to the original GWO and its variants.
