Matrix Formulation of EISs of Graphs and Its Application to WSN Covering Problems
In this paper, the problem of formulating and finding externally independent sets of graphs is considered by using a newly developed STP method, called semitensor product of matrices. By introducing a characteristic value of a vertex subset of a graph and using the algebraic representation of pseudo...
