Outline of Annual Research Achievements

最終年度である令和4年度は、国際会議とジャーナル論文への発表を積極的に実施した。大きくは、グラフ上で定義される各種の問題に対する結果と、より幾何的な計算幾何の問題に対する結果に分けることができる。それぞれの分野における問題に対して、計算複雑度を示すことと、具体的な効率の良いアルゴリズムを与えることという2つのアプローチを行い、多くの結果を得ることができた。
グラフ上での問題については、組合せ遷移と呼ばれる分野に分類される問題に対する結果を数多く得ることができた。またNP完全問題やNP困難問題と呼ばれる、理論的に手に負えないとされる問題に対しても、近年活発に研究されている固定パラメータ容易性と呼ばれるアプローチにより、効率の良いアルゴリズムを数多く得ることができた。
計算幾何の問題については、計算折り紙と呼ばれる分野の問題に対する結果を多数得ることができた。特に、展開図とそれを折ることで得られる立体の間の関係について、いくつかの重要な結果が得られた。例えば、「辺をどのように切り開いても必ず重なりを持ってしまう多面体」について、従来知られていたものよりも遥かに小さな具体例が存在することを証明した。また、「多面体を切り開いて得られる展開図から、別の多面体を折ることができるか」という問題について、新たな研究課題を開拓し、非自明な結果を多数得ることができた。
これらの研究テーマは、世界的に見ても最先端の研究課題と新たな研究成果であり、多くの国際共著論文を書くことができ、本研究グループの生産性の高さと研究成果の質の高さを世界レベルでアピールすることができた。
