Webif it has the minimum length among all possible edit paths. Deﬁnition 2 (Graph Edit Distance). Given two graphs G and Q, the graph edit distance between them, denoted by ged(G;Q), is the length of an optimal edit path that trans-forms Gto Q(or vice versa). Example 1. In Figure 1, we show an optimal edit path Pthat transforms graph Gto graph Q. WebReturns GED (graph edit distance) between graphs G1 and G2. Graph edit distance is a graph similarity measure analogous to Levenshtein distance for strings. It is defined as minimum cost of edit path (sequence of node and edge edit operations) transforming graph G1 to graph isomorphic to G2. roth plastik
