The book "A Hybrid Cat Optimization and K-Median for Solving Community Detection" offers a comprehensive analysis of methods for detecting community structures in networks, a central theme in social network analysis. The authors, Amany A. Naem, Lamiaa M. El Bakrawy, and Neveen I. Ghali, present innovative approaches to network clustering aimed at identifying similar clusters. By combining hybrid cat optimization and K-median methods, an optimized approach to community detection is introduced, with modularity serving as the objective measure. This specialized book is aimed at researchers and practitioners involved in the analysis of complex networks and the optimization of clustering methods.
