The study is focused to present a Genetic Algorithm (GA) that is tested with the sample problems extract from the open literature. The evaluation of GA is carried out against the modified ART1, K-means and C-linkage algorithm that are well known from the literature sources as well. To measure, the performance of the CF algorithms, group efficiency is calculated based on number of exceptional elements and workload.
