Graph fibrations, graph isomorphism, and PageRank
PageRank is a ranking method that assigns scores to web pages using the limit distribution of a random walk on the web graph. A fibration of graphs is a morphism that is a local isomorphism of inneighbourhoods, much in the same way a covering projection is a local isomorphism of neighbourhoods. We show that a deep connection relates fibrations and Markov chains with restart, a particular kind o...
متن کاملGraph Invariants and Graph Isomorphism
In graph theory, Graph Isomorphism is an important issue. Information in the database can be stored in the form of graph. Graph represents the structural information in an efficient way. Graph Isomorphism problem is to determine if there exists one to one correspondence between the structures of two graphs. Graph isomorphism problem arises in many fields such as chemistry, switching theory, inf...
متن کاملGraph Isomorphism
While in general it is not known whether there is a polynomial time algorithm to decide whether two given graphs are isomorphic, there are polynomial-time algorithms for certain subsets of graphs, including but not limited to planar graphs and graphs with bounded valence. In this thesis, we will give a brief introduction on the Graph Isomorphism Problem and its relations to complexity theory. W...
متن کاملOn Graph Isomorphism for Restricted Graph Classes
Graph isomorphism (GI) is one of the few remaining problems in NP whose complexity status couldn’t be solved by classifying it as being either NP-complete or solvable in P. Nevertheless, efficient (polynomial-time or even NC) algorithms for restricted versions of GI have been found over the last four decades. Depending on the graph class, the design and analysis of algorithms for GI use tools f...
متن کاملWeb Graph and PageRank algorithm
The pages and hyperlinks of the World-Wide Web may be viewed as nodes and arcs in a directed graph. This graph has about a billion nodes today, several billion links, and appears to grow exponentially with time. Known facts about macroscopic structure, diameter and in-degree and out-degree distributions of the graph are reviewed. The PageRank as another way of characterizing structure of the We...
