House of Graphs: A Database of Interesting Graphs

Free registration required

Executive Summary

In this paper, the authors present House of Graphs which is a new database of graphs. The key principle is to have a searchable database and offer next to complete lists of some graph classes also a list of special graphs that already turned out to be interesting and relevant in the study of graph theoretic problems or as counterexamples to conjectures. This list can be extended by users of the database. Graphs are given as adjacency lists, sometimes with, sometimes without additional data and in various formats. Such lists can serve as a source for intuition when one studies some conjecture and even as a possible source for counterexamples.
