Chordal graphs

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

A graph is chordal if every cycle of length at least 4 has a chord, an edge between two non-consecutive vertices of the cycle. After reviewing some of the fundamental properties and characterizations of chordal graphs, we present significant developments obtained over recent years, both algorithmic and graph-theoretic. Chordal graphs form one of the earliest families for which structural properties fundamentally help in solving many NP-hard problems efficiently. They also lead to the development of the notion of tree-width and partial k-trees. Chordal graphs appear in numerous applications in algorithmic graph theory, computer science and optimization.
