Algorithmic and Applied Aspects of Network Domination

Project Description: This project explores various domination problems in graphs, including the classic Dominating Set problem, the Connected Dominating Set problem, and Roman Domination Functions. Our study explores a wide range of algorithmic approaches, from optimization and enumeration techniques to parameterized complexity analysis, identifying cases where these problems become more tractable. We also investigate efficient algorithms for special graph classes. In addition to theoretical work, we examine real-world applications of domination-related problems, particularly in biological networks (e.g., controllability analysis) and social networks (e.g., influence propagation). By combining the study of (theoretical) graph algorithms with practical applications, this research contributes to both foundational and applied domains of network science and data analysis.
