This paper presents our submission to ML4CO, a branching rule that exploits the structure within a problem class via a graph neural network that is trained using a distributional reinforcement learning algorithm. The learned branching rule participated in the dual bound challenge, ranking third among 23 entries. Experiments on the ML4CO instances show that it performs between 16% and 34% better on average than the default reliability pseudocost branching in the state-of-the-art academic solver SCIP.
