Linear time algorithm for the vertex-edge domination problem in convex bipartite graphs

Y Büyükçolak - Discrete Optimization, 2025 - Elsevier
Given a graph G=(V, E), a vertex u∈ V ve-dominates all edges incident to any vertex in the
closed neighborhood N [u]. A subset D⊆ V is a vertex-edge dominating set if, for each edge …

Disjoint isolating sets and graphs with maximum isolation number
