Outline of Research at the Start

グラフ最適化問題は工学,情報学,経済学をはじめとした様々な分野における自然な問題としてしばしば現れる.それらの多くは,現実的な時間で解を求めることが難しいと考えられているが,近似アルゴリズムやパラメータ化アルゴリズムといった高性能アルゴリズム設計手法の発展によって,ある程度効率的に解を求めることが可能になった.近年では,これらに加えて,高速高精度なパラメータ化近似アルゴリズムが注目されている.
本研究では,一般に広く研究されている重み無し無向グラフのみならず,重み付き有向グラフなどのより記述力の高いグラフに対する高速高精度グラフアルゴリズムの設計を目指す.

Outline of Final Research Achievements

Many real-world problems are formulated as graph optimization problems on directed and weighted graphs. However, they are often more complex than graph optimization problems on undirected and unweighted graphs. In this research, we designed efficient and high-accurate algorithms for various graph optimization problems defined not only on undirected and unweighted graphs, but also on weighted graphs, directed graphs, and weighted directed graphs, by using approximation and parameterization techniques.

Academic Significance and Societal Importance of the Research Achievements

実ネットワークの中には,重みや辺の向きが重要なものも多数存在する.例えば,交通ネットワーク,取引ネットワーク,人物ネットワーク(社会ネットワーク)などである.これらの実ネットワークを対象とした問題の多くは計算困難であるため,重み付き有向グラフ最適化問題等に対して,効率的に高精度の解を求めるアルゴリズムの実現は学術的・社会的意義がある.
