On the editing distance of graphs [PDF]

open access: yesJournal of Graph Theory, 2008
AbstractAn edge‐operation on a graph G is defined to be either the deletion of an existing edge or the addition of a nonexisting edge. Given a family of graphs $\cal G$, the editing distance from G to $\cal G$ is the smallest number of edge‐operations needed to modify G into a graph from $\cal G$.

String Edit Distance, Random Walks and Graph Matching [PDF]

open access: yesInternational Journal of Pattern Recognition and Artificial Intelligence, 2002
This paper shows how the eigenstructure of the adjacency matrix can be used for the purposes of robust graph matching. We commence from the observation that the leading eigenvector of a transition probability matrix is the steady state of the associated Markov chain.

Revisiting the complexity of and algorithms for the graph traversal edit distance and its variants

open access: yesAlgorithms for Molecular Biology
The graph traversal edit distance (GTED), introduced by Ebrahimpour Boroojeny et al. (2018), is an elegant distance measure defined as the minimum edit distance between strings reconstructed from Eulerian trails in two edge-labeled graphs.

On the Complexity of Exact Pattern Matching in Graphs: Binary Strings and Bounded Degree [PDF]

open access: yes, 2019
Exact pattern matching in labeled graphs is the problem of searching paths of a graph $G=(V,E)$ that spell the same string as the pattern $P[1..m]$.

If the Current Clique Algorithms are Optimal, so is Valiant's Parser

open access: yes, 2015
The CFG recognition problem is: given a context-free grammar $\mathcal{G}$ and a string $w$ of length $n$, decide if $w$ can be obtained from $\mathcal{G}$. This is the most basic parsing question and is a core computer science problem.
