Outline of Final Research Achievements

We studied algorithmic techniques and hardness of several problems related to infinite scheduling, covering problems, and optimization in multi-party settings. We obtained some new algorithms and theoretical bounds for problems of the following types: searching problems on graphs, patrolling problems on graphs, games between the patrollers and the intruder on graphs, competitive diffusion on networks, hedonic games on graphs, reconfiguration problems on graphs, and periodic scheduling of jobs.

Academic Significance and Societal Importance of the Research Achievements

本研究では、問題設定の記述そのものは単純だが、満すべき目標として「恒常的に保守する」「連続的に漏れなくカバーする」といった安全・安定の要求を課する問題、あるいは多主体がおのおの自己の利益を求めて行動することが最適化に新たな複雑さを呈する問題について、理論的分析を行った。現実的な状況を含んでいると考えられるこれらの問題のいくつかについて、計算手法と困難さの両面から解明が進んだ。
