Outline of Research at the Start

本研究は理論的な側面と実験的な側面のいずれも取り扱う.
理論的な側面としては既存の木分解に基づくメタアルゴリズムの結果を集合・関係・代数といった方法での記述可能性を調べる.特に,後にメタアルゴリズムをソフトウェア化することを意識して理論構築を行う.
実験的な側面については,既存の木分解上の様々な動的計画法を実装しながら,そこに現れる共通構造を理論的な側面にフィードバックしながら研究を行っていく.

Outline of Final Research Achievements

The purpose of this work is to study fast algorithmic meta-theorems for tree decomposable graphs. As parts of this work, we give (1) a generic designing scheme for enumeration algorithms, (2) several algorithmic techniques based on vertex integrity, and (3) algorithmic meta-theorems for reconfiguration problems. Although the result of (2) is not considered as a "meta-theorem", it would stimulate a successive study on fast algorithmic meta-theorems for vertex integrity, given by other researchers.

Academic Significance and Societal Importance of the Research Achievements

現段階では理論的な研究に留まっているが,これらの成果に基づいて実用的な研究が進めることで社会へ貢献ができるため,その社会的な意義があると考えられる.また,本研究の理論研究の一部が発端となり,さらなる研究が国内外の研究者から行われ始めていることを鑑みると,その学術的な意義は十分にあると考えられる.
