ゼロサプレス型二分決定グラフを用いた解空間の圧縮保持によりグラフ最適化問題を解くアルゴリズムの設計と評価
(English)
Design and evaluation of algorithms that solve graph optimization programs using zero-suppressed binary decision diagrams
Overview of the research
(Japanese)
ゼロサプレス型二分決定グラフは集合族を圧縮して効率良く保持するデータ構造である。与えられたグラフに対して、グラフ上のパスや全域木などの様々な部分グラフ構造を列挙して、ゼロサプレス型二分決定グラフを用いて圧縮された状態で保持を行うアルゴリズムの設計と評価を行う。一票の格差の小さな選挙区割の求解や、災害からの避難時間を短くする避難所割当などの社会システム設計に現れるグラフ最適化問題への応用に関する研究も行う。
(English)
A zero-suppressed binary decision diagram is a data structure that compactly and efficiently represents a family of sets. I have been researching design and evaluation of algorithms that enumerate subgraph structures of a given graph such as paths and spanning forests, and that store them into zero-suppressed binary decision diagrams. I have also been researching graph optimization problems such as political redistricting and evacuation planning as applications of my algorithms.
