Research Abstract |
In modern society, we have many networks such as traffic networks and communication networks. It is required that such networks have some fault-tolerance. The concepts of graph connectivity are known as one measure of network fault-tolerance. In this research, we proposed several efficient algorithms for connectivity augmentation problems and source location problems, which are well-known as graph problems concerning connectivity. Also, we generalized these results, which may contribute to the analysis of other problems.
