The Order/degree Problem Competition
Graph Golf is an international competition of the degree-order problem since 2015. It is conducted with the goal of making a catalog of smallest-diameter graphs for every order/degree pair. Anyone in the world can take part in the competition by submitting a graph. Outstanding authors will be awarded in CANDAR'15, an international conference held in Sapporo, Japan, in December 2015. Please see Graph Golf for the details.
