Algorithms for Generating Strongly Chordal Graphs

Lecture Notes in Computer Science, 2021
Graph generation serves many useful purposes: cataloguing, testing conjectures, to which we would like to add that of producing test instances for graph algorithms. Strongly chordal graphs are a subclass of chordal graphs for which polynomial-time algorithms could be designed for problems which are NP-complete for the parent class of chordal graphs. In

Tractability of Parameterized Completion Problems on Chordal, Strongly Chordal, and Proper Interval Graphs

SIAM Journal on Computing, 1999
Summary: We study the parameterized complexity of three NP-hard graph completion problems. The minimum fill-in problem asks if a graph can be triangulated by adding at most \(k\) edges. We develop \(O(c^k m)\) and \(O(k^2 mn+f(k))\) algorithms for this problem on a graph with \(n\) vertices and \(m\) edges. Here \(f(k)\) is exponential in \(k\) and the
