Graphisomorphismus
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. Graph isomorphism is an equivalence relation on graphs and as such it partitions the class of all graphs into equivalence classes. A set of graphs isomorphic to each other is called an isomorphism class of graphs.

WebA graph isomorphism is a bijection between the vertex sets of two graphs such that two vertices in one graph are adjacent if and only if the corresponding two vertices in the other graph are adjacent. Isomorphic graphs are viewed as being the same graph. Within a graph, two vertices that are joined by an edge are said to be adjacent, or neighbours.
