The Evolutionary Clustering (EC) algorithm presented in this paper is based on a (\mu,\lambda)-Evolution Strategy where the object variables of genotypes are the centers of clusters. In the experimental section we compare the segmentation obtained by the application of C-Means (CM) algorithm and two variants of EC to a simple data set consisting of a multimodal transverse slice from a MRI head acquisition volume. EC obtains more stable solutions than CM, and, as it can take into account the cardinality of clusters, dramatically improves the quality of segmentation results.

Abstract
The Evolutionary Clustering (EC) algorithm presented in this paper is based on a (\mu,\lambda)-Evolution Strategy where the object variables of genotypes are the centers of clusters. In the experimental section we compare the segmentation obtained by the application of C-Means (CM) algorithm and two variants of EC to a simple data set consisting of a multimodal transverse slice from a MRI head acquisition volume. EC obtains more stable solutions than CM, and, as it can take into account the cardinality of clusters, dramatically improves the quality of segmentation results.File in questo prodotto:
