Abstract

The edit distance between two graphs on the same labeled vertex set is the size of the symmetric difference of the edge sets. The edit distance function of the hereditary property, HH, is a function of p∈[0,1]p∈[0,1] and is the limit of the maximum normalized distance between a graph of density pp and HH.This paper uses the symmetrization method of Sidorenko in order to compute the edit distance function of various hereditary properties. For any graph HH, Forb(H) denotes the property of not having an induced copy of HH. We compute the edit distance function for Forb(H), where HH is any split graph, and the graph H9H9, a graph first used to describe the difficulties in computing the edit distance function.
