Outline of Final Research Achievements |
Most important combinatorial optimization problems are computationally intractable (NP-hard), i.e., there are no algorithm to find optimal solutions to such problems in polynoial time. The contributions of this research are mainly divided into the following two: (1) We designed approximation and/or fixed-parameter algorithms for optimization problems with weaker constraints, and (2) efficient algorithms for optimization problems with stronger constraints.

Academic Significance and Societal Importance of the Research Achievements |
生産計画やスケジューリング問題は,組合せ最適化問題として捉えることができ,所望の解を求めなければならない状況が頻繁にある.しかし,多くは計算困難となってしまうため,得られる解の品質や高速に解くことができる入力に関して,ある程度の正確性を捨て,許容出来る解を求める必要がある.本研究課題は,組合せ最適化問題の条件強化と緩和によって効率の良いアルゴリズム設計を実現していることに学術的・社会的意義がある.
