is called Graph Isomorphism Problem (GI). One of striking facts about GI is the following established by Whitney in s. Theorem 1. Two connected graphs are isomorphic if and only if their line graphs are isomorphic, with a single exception: K 3 and K 1;3, which are not isomorphic but both have K 3 as their line graph. nections of the graph isomorphism problem with other problems are examined. INTRODUCTION. Below, the term "graph" denotes a finite nondirected graph without loops and multiple. edges, and complexity of operation of an algorithm denotes the number of elementary operations. implemented by this algorithm in the worst case.

Report of Dagstuhl Seminar The Graph Isomorphism Problem Edited by László Babai1, Anuj Dawar2, Pascal Schweitzer3, and Jacobo Torán4 1University of Chicago, US, [email protected] Graphs, isomorphism, NP-intermediate status A graph is a set (the set of vertices) endowed with an irre exive, symmetric binary relation called adjacency. Isomorphisms are adjacency-preseving bi-jections between the sets of vertices. The Graph Isomorphism (GI) problem asks to determine whether two given graphs are isomorphic.Abstract—Graph isomorphism is an important computer sci- ence problem. The problem for the general case is unknown to be in polynomial. The Graph Isomorphism Problem remains one of the two unresolved computational .. URL cocorosie-tales-of-grass-widow-adobe.com .pdf.
