Samen vormen ze een unieke vingerafdruk. We propose a new graph convolutional neural network model for learning branch-and-bound variable selection policies, which leverages the natural variable-constraint bipartite graph representation of mixed-integer linear programs. Together they form a unique fingerprint.
