Haj\'os' cycle conjecture for small graphs

Combinatorics 2017-05-25 v1

Abstract

Haj\'os' conjecture states that an Eulerian graph of order n can be decomposed into at most (n-1)/2 edge-disjoint cycles. We describe preprocessing steps, heuristics and integer programming techniques that enable us to verify Haj\'os' conjecture for all Eulerian graphs with up to twelve nodes.
