Graphisomorphismus
The graph isomorphism problem is the computational problem of determining whether two finite graphs are isomorphic. The problem is not known to be solvable in polynomial time nor to be NP-complete, and therefore may be in the computational complexity class NP-intermediate. It is known that the graph isomorphism problem is in the low hierarchy of class NP, which implies that it is not NP-complete … WebThe Graph Isomorphism (GI) problem asks to determine whether two given graphs are isomorphic. It is known that graphs are universal among explicit nite structures in the sense that the isomorphism problem for explicit structures can be reduced in polynomial time to GI (in the sense of Karp-reductions1) [HP,

WebThis project under @msstate-dasi provides a subgraph isomorphism Java plugin for Neo4j database. Given a query graph and a target graph, it calculates all possible subgraphs of the target graph isomorphic to the query graph. Both the query graph and target graph are stored in the same Neo4j database.
