Finding cohesive subgraphs in a network has been investigated in many network mining applications. Several alternative formulations of cohesive subgraph have been proposed, a notable one of them is $s$-club, which is a subgraph whose diameter is at most

On some covering graphs of a graph [PDF]
For a graph $G$ with vertex set $V(G)=\{v_1, v_2, \dots, v_n\}$, let $S$ be the covering set of $G$ having the maximum degree over all the minimum covering sets of $G$.

Soft document clustering using a novel graph covering approach [PDF]
Background In text mining, document clustering describes the efforts to assign unstructured documents to clusters, which in turn usually refer to topics. Clustering is widely used in science for data retrieval and organisation.

AbstractGiven a finite simple graph , an odd cover of is a collection of complete bipartite graphs, or bicliques, in which each edge of appears in an odd number of bicliques, and each nonedge of appears in an even number of bicliques. We denote the minimum cardinality of an odd cover of by and prove that is bounded below by half of the rank over

New Concepts of Vertex Covering in Cubic Graphs with Its Applications
Graphs serve as one of the main tools for the mathematical modeling of various human problems. Fuzzy graphs have the ability to solve uncertain and ambiguous problems.

The topological ordering of covering nodes [PDF]
The topological ordering algorithm sorts nodes of a directed graph such that the order of the tail of each arc is lower than the order of its head. In this paper, we introduce the notion of covering between nodes of a directed graph. Then, we apply the

On the Edge Covering Transversal Edge Domination in Graphs
Let G = (V,E) be any graph with nvertices and medges. An edge dominating set which intersects every minimum edge covering set in a graph Gis called an edge covering transversal edge dominating set of G.

On Edge H-Irregularity Strengths of Some Graphs
For a graph G an edge-covering of G is a family of subgraphs H1, H2, . . . , Ht such that each edge of E(G) belongs to at least one of the subgraphs Hi, i = 1, 2, . . . , t. In this case we say that G admits an (H1, H2, . . . , Ht)-(edge) covering.
