Outline of Final Research Achievements

Optimization methods, which find good solutions from many candidates, are the core technologies of this research. In this research, we focused on optimization methods with respect to discrete structures such as networks. Especially, we aimed at theoretical developments of network optimization methods based on submodular optimization. Submodularity can be regarded as a discrete version of convexity. In addition to basic theory, we applied network optimization methods to problems in machine learning, artificial intelligence, and so on. In this way, we worked on building basic technologies for optimization theory for solving problems in modern society, and designed efficient network optimization algorithms.
