The most stringent pattern of exact-matching algorithms is graph isomorphism
, which requires the mapping of nodes and edges on both graphs to bebijections .
Thus, [empty set] is a Neutrosophic graph isomorphism
from Ne(G, I) onto Ne(G', I'), that is, Ne(G, I) [congruent to] Ne(G', I').
The first one provides the results of graph isomorphism
. The second describes the relation between edge conditions of the Farey graph F and the Farey sequences.
Meanwhile, in  an algorithm for graph isomorphism
at large scale is shown.
In the structural synthesis process of gear train kinematic chains, correctly identifying graph isomorphism
is an important step which generates new structural types.
(This is expected, as computing graph isomorphism
remains a computationally challenging problem.
A new algorithm efficiently solves the graph isomorphism
problem, computer scientist Laszlo Babai announced November 10 at a Combinatorics and Theoretical Computer Science seminar at the University of Chicago.
By computer search, we find that there is one modular Leech tree for n = 8 and the edge-weighting function is unique, up to group and graph isomorphism
. It is shown in Figure 3.
Graph automorphism (GA), graph isomorphism
(GI), and finding of a canonical labeling (CL) are closely related classical graph problems that have applications in many fields, ranging from mathematical chemistry [1, 2] to computer vision .

This example is a particular instance of the graph isomorphism
problem, for which there is no polynomial time algorithm yet, while our algorithm seems to solve the problem.
