WebDec 14, 2014 · Subgraph isomorphism problem)是NP-complete问题 [图同构](Graph isomorphism)是NP问题，但是既没有人找到多项式算法(证明是P问题)，也没有人能证明是NP-complete问题。 我们可以用Hash的方法以一定的概率确定两图是否同构。 1.杨弋《Hash在信息学竞赛中的一类应用》 WebLet G1 and G2 be any two non-isomorphic graphs. If a graph neural network A : G → RdR^d R d maps G1 and G2 to different embeddings, the Weisfeiler-Lehman graph isomorphism test also decides G1 and G2 are not isomorphic. 可以用反证法证明这条结论，这个引理说明了WL test是GNN的性能上界。 定理一 Let A : G → RdR^d R ...
