Equitable Graph of a Graph [PDF]
Proyecciones (Antofagasta), 2012 A subset D of V is called an equitable dominating set if for every v ∈ V − D there exists a vertex u ∈ D such that uv ∈ E(G) and |d(u) − d(v)| ≤ 1 ,w hered(u) denotes the degree of vertex u and d(v) denotes the degree of vertex v. The minimum cardinality of such a dominating set is denoted by γ e and is called the equitable domination number of G ...

Orthogonality for (0, −1) tropical normal matrices
Special Matrices, 2020 We study pairs of mutually orthogonal normal matrices with respect to tropical multiplication. Minimal orthogonal pairs are characterized. The diameter and girth of three graphs arising from the orthogonality equivalence relation are computed.

THE k-INDEPENDENT GRAPH OF A GRAPH [PDF]
Advances and Applications in Discrete Mathematics, 2017 Let $G=(V,E)$ be a simple graph. A set $I\subseteq V$ is an independent set, if no two of its members are adjacent in $G$. The $k$-independent graph of $G$, $I_k (G)$, is defined to be the graph whose vertices correspond to the independent sets of $G$ that have cardinality at most $k$.

Variable neighborhood search for minimum linear arrangement problem [PDF]
Yugoslav Journal of Operations Research, 2016 The minimum linear arrangement problem is widely used and studied in many practical and theoretical applications. It consists of finding an embedding of the nodes of a graph on the line such that the sum of the resulting edge lengths is ...

IEEE Access, 2023 Heuristic search algorithms are informed search strategies that use heuristics to estimate the minimal cost of the path from the current state to the goal. Using this additional knowledge, this type of algorithms can distinguish non-goal states, and then
