Fitness sharing based niching methods have been widely applied to multimodal optimization. However, they often suffer from the so-called niche radius problem as an improper selection of the niche radius may easily lead to suboptimal performance. To address such a problem, a diverse niche radii mechanism has been proposed in this paper. In the proposed algorithm, the radius of each niche will be individually...
Partitional clustering is a common approach to cluster analysis. Although many algorithms have been proposed, partitional clustering remains a challenging problem with respect to the reliability and efficiency of recovering high quality solutions in terms of its criterion functions. In this paper, we propose a niching genetic k-means algorithm (NGKA) for partitional clustering, which aims at reliably...
