Dominating set is one of the graph theoretical structures and has many important applications such as clustering, intrusion detection and backbone formation in wireless sensor networks; placement of gateways in wireless mesh networks; summarizing multiple documents and selecting queries for information retrieval on the internet. Finding the minimum weighted connected dominating set is an NP-Hard problem. Hence, approximation algorithms and meta-heuristic algorithms can give effective results in polynomial time. In this book, different meta-heuristic algorithms are studied for the minimum weighted connected dominating set problem.
