Graph Neural Networks (GNNs) have been widely used in relational and symbolic domains, with widespread application of GNNs in combinatorial optimization, constraint satisfaction, relational reasoning and other scien-tific domains. deep neural networks (DNNs) with dynamic programming to solve combinatorial optimization problems. A generic five-stage pipeline for end-to-end learning of combinatorial problems on graphs 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 … /MediaBox [ 0 0 612 792 ] Exact Combinatorial Optimization with Graph Convolutional Neural Networks. stream /Annots [ 235 0 R ] The other main neural network approach to combinatorial optimization is based on Kohonen’s Self-Organizing Feature Map. “ Erdős goes neural: an unsupervised learning framework for combinatorial optimization on graphs ” ( bibtex ), that has been accepted for an oral contribution at NeurIPS 2020.
