On the computation of edit distance functions
The edit distance between two graphs on the same labeled vertex set is the symmetric difference of the edge sets. The edit distance function of hereditary property, H, is a function of p ∈ [0, 1] and is the limit of the maximum normalized distance between a graph of density p and H. This paper uses localization, for computing the edit distance function of various hereditary properties. For any ...
متن کاملHomomorphic Computation of Edit Distance
These days genomic sequence analysis provides a key way of understanding the biology of an organism. However, since these sequences contain much private information, it can be very dangerous to reveal any part of them. It is desirable to protect this sensitive information when performing sequence analysis in public. As a first step in this direction, we present a method to perform the edit dist...
متن کاملEdit Distance and its Computation
In this paper, we provide a method for determining the asymptotic value of the maximum edit distance from a given hereditary property. This method permits the edit distance to be computed without using Szemerédi’s Regularity Lemma directly. Using this new method, we are able to compute the edit distance from hereditary properties for which it was previously unknown. For some graphs H, the edit ...
متن کاملComputation of Normalized Edit Distance and Applications
Given two strings X and Y over a finite alphabet, the normalized edit distance between X and Y, d( X , Y ) is defined as the minimum of W ( P ) / L ( P ) , where P is an editing path between X and Y , W ( P ) is the sum of the weights of the elementary edit operations of P, and L ( P ) is the number of these operations (length of P). In this paper, it is shown that in general, d ( X , Y ) canno...
متن کاملFast Computation of Graph Edit Distance
The graph edit distance (GED) is a well-established distance measure widely used in many applications. However, existing methods for the GED computation suffer from several drawbacks including oversized search space, huge memory consumption, and lots of expensive backtracking. In this paper, we present BSS GED, a novel vertex-based mapping method for the GED computation. First, we create a smal...
