In mathematics and computer science, graph edit distance (GED) is a measure of similarity (or dissimilarity) between two graphs. The concept of graph edit distance was first formalized mathematically by Alberto Sanfeliu and King-Sun Fu in 1983. A major application of graph edit distance is in inexact graph matching, such as error-tolerant pattern recognition in machine learning. The graph edit distance between two graphs is related to the string edit distance between strings. … Webtree edit distance is deﬁned as the cost associated with a sequence of edit operations that transforms one tree into another while minimizing the total cost. We now introduce …

The edit distance focuses on finding an isomorphism between graphs/subgraphs, while for merge trees we can have two isomorphic trees with a positive distance (see the … WebEdit distance. In computational linguistics and computer science, edit distance is a string metric, i.e. a way of quantifying how dissimilar two strings (e.g., words) are to one another, that is measured by counting the minimum number of operations required to transform one string into the other.
