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

Theory and Design of Joint Time-Vertex Nonsubsampled Filter Banks
IEEE Transactions on Signal Processing, 2021Graph signal processing (GSP) is a field that deals with data residing on irregular domains, i.e. graph signals. In this field, the graph filter bank is one of the most important developments, owing to its ability to provide multiresolution analysis of ...

The average size of a connected vertex set of a graph—Explicit formulas and open problems
Journal of Graph Theory, 2020Although connectivity is a basic concept in graph theory, the enumeration of connected subgraphs of a graph has only recently received attention. The topic of this paper is the average order of a connected induced subgraph of a graph.

Optimal PMU placement solution: graph theory and MCDM-based approach
, 2017In this study, a new method using graph theory and analytical hierarchy process (AHP)-based multi-criteria decision making approach has been proposed to solve optimal phasor measurement unit (PMU) placement (OPP) problem for complete network ...
