Social Network Analysis Using Cultural Algorithms And Its Variants, Pooya Moradian Zadeh
Social Network Analysis Using Cultural Algorithms And Its Variants, Pooya Moradian Zadeh
Electronic Theses and Dissertations
Finding relationships between social entities and discovering the underlying structures of networks are fundamental tasks for analyzing social networks. In recent years, various methods have been suggested to study these networks efficiently, however, due to the dynamic and complex nature that these networks have, a lot of open problems still exist in the field. The aim of this research is to propose an integrated computational model to study the structure and behavior of the complex social network. The focus of this research work is on two major classic problems in the field which are called community detection and link prediction. …
Improving Robustness In Social Fabric-Based Cultural Algorithms, Bahram Zaeri
Improving Robustness In Social Fabric-Based Cultural Algorithms, Bahram Zaeri
Electronic Theses and Dissertations
In this thesis, we propose two new approaches which aim at improving robustness in social fabric-based cultural algorithms. Robustness is one of the most significant issues when designing evolutionary algorithms. These algorithms should be capable of adapting themselves to various search landscapes. In the first proposed approach, we utilize the dynamics of social interactions in solving complex and multi-modal problems. In the literature of Cultural Algorithms, Social fabric has been suggested as a new method to use social phenomena to improve the search process of CAs. In this research, we introduce the Irregular Neighborhood Restructuring as a new adaptive method …
