A rough set method for the vertex cover problem in graph theory
Journal of Intelligent & Fuzzy Systems, 2016In 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.

[Most frequent themes in Editorials of Vertex journal (1990-2019) analyzed by graph theory].
Vertex (Buenos Aires, Argentina), 2022The analysis of Editorials is a little explored topic, which can facilitate the understanding of historical processes and changes in Psychiatry. In the case of de Vertex Revista Argentina de Psiquiatría, the Editorials were written by the same person for 30 years. The most frequently used thematic areas were studied, using graph theory, to characterize

Relation algebras and vertex conditions in graph theory
2018The 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
