Relation algebras and vertex conditions in graph theory

open access: gold, 2018
The scheme associated with a graph is an association scheme iff the graph is strongly regular. Consider the problem of extending such an association scheme to a superscheme. The obstacles can be expressed in terms of f-vertex conditions. If a graph does not satisfy the i-vertex condition, a presuperscheme associated with it cannot be erected beyond the

A rough set method for the vertex cover problem in graph theory

open access: closedJournal of Intelligent & Fuzzy Systems, 2016
In this paper, we first establish a Multi-Relation Granular Computing model by a given graph, and point out that all the reducts of the constructed Multi-Relation Granular Computing model are exactly all the minimal vertex covers of the corresponding graph.
