A practical heuristic for finding graph minors

10 Jun 2014 · Jun Cai, William G. Macready, Aidan Roy ·

We present a heuristic algorithm for finding a graph $H$ as a minor of a graph $G$ that is practical for sparse $G$ and $H$ with hundreds of vertices. We also explain the practical importance of finding graph minors in mapping quadratic pseudo-boolean optimization problems onto an adiabatic quantum annealer.
