The graph isomorphism problem (GI) plays a central role in the theory of computational complexity and has importance in physics and chemistry as well \cite{kobler93,fortin96}. No polynomial-time ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

Abstract: Graph isomorphism is an essential problem in graph theory and widely used in a variety of applications. With graph size increasing, graph isomorphism become difficult for classical ...

Graph theory is the study of networks and connections between variables. In the real world it has uses from powering search engine algorithms to fixing airline scheduling. Now, scientists are using it ...

Collection of MATLAB files covering multiple implementations of mathematical algorithms in various domains, including numerical methods, advanced linear algebra, and discrete mathematics.

Abstract: Maximum common sub-graph isomorphism (MCS) is a famous NP-hard problem in graph processing. The problem has found application in many areas where the similarity of graphs is important, for ...

A state of the art algorithm for the Graph Isomorphism problem, adjusted for Sub-Graph and Induced Sub-Graph Isomorphism and extended to directed and multigraph settings.
