WebIn the mathematical discipline of graph theory, a 3-dimensional matching is a generalization of bipartite matching (also known as 2-dimensional matching) to 3-partite hypergraphs, which consist of hyperedges each of which contains 3 vertices (instead of edges containing 2 vertices in a usual graph). Webproblem, i.e., the classic graph matching problem1, and provide a formal deﬁnition of the graph matching problem. Subsequently, we will focus discussion on state-of-the-art graph matching models based on deep learning as well as more advanced GNNs in the literature. 1 For simplicity, we represent the classic graph matching problem as the ... if you living in a glass house
