C-cordial labeling of line signed graphs-I

AIP Conference Proceedings, 2020
Let S=(G, σ) be a signed graph. S admits C-cordial labeling if the difference between the number of negative and positive edges (vertices) differ by at most one under canonical marking of S. In this paper, we characterize signed paths and cycles having given number of negative sections where the line signed graphs admit C-cordial labeling.

Signed graph based approach for on-line optimization in cognitive networks

2011 Third International Conference on Communication Systems and Networks (COMSNETS 2011), 2011
One of the major architectural components shared between cognitive radios and networks is a cognitive engine supporting a cognitive process. Many of the decision making will need an optimization core for determining the optimum assignment for the control variables.

Canonical Consistency of Semi-Total Line Signed Graphs

National Academy Science Letters, 2015
A signed graph (or sigraph in short) is an ordered pair \(S = (S^u, \sigma )\), where \(S^u\) is a graph \(G = (V, E)\) and \(\sigma :E\rightarrow \{+,-\}\) is a function from the edge set \(E\) of \(S^u\) into the set \(\{+, -\}\). The canonical marking on \(S\) is defined as: for each vertex \(v \in V(S)\), \(\displaystyle \mu _\sigma (v) = \prod _ ...
