Idea: A vertex cover must contain at least one vertex from each pair 32 Vertex cover (reduction continued) • Clause-satisfaction components : Three vertices for each clause, connected to each other
- What is: Vertex Cover - Understanding Graph Theory
Vertex Cover is a fundamental concept in graph theory, which refers to a set of vertices in a graph such that every edge in the graph is incident to at least one vertex from this set In simpler terms, if you have a graph made up of nodes (vertices) connected by lines (edges), a vertex cover ensures that every line has at least one of its
- Vertex Cover | Brilliant Math Science Wiki
A vertex cover of a graph \(G\) is a set, \(V_c\), of vertices in \(G\) such that every edge of \(G\) has at least one of vertex in \(V_c\) as an endpoint This means that every vertex in the graph is touching at least one edge

To illustrate this concept of polynomial time reduction, we will look at the decision and opti-mization versions of the Vertex Cover problem Given a graph G = (V; E), we say a set of vertices S V is a vertex cover if every edge e 2 E has at least one end in S
- An overview of graph covering and partitioning - ScienceDirect
An edge (resp vertex) covering is a set of templates such that each edge (resp vertex) of the host graph belongs to at least one template In addition, there is a measure for the quality of a covering, e g , the number of used templates

Two vertices in a simple graph are said to be adjacent if they are joined by an edge, and an edge is said to be incident to the vertices it joins The number of edges incident to a vertex v is called the degree of the vertex and is denoted by deg v ; equivalently, the degree of a vertex is equals the number of vertices adjacent to it

Definition A graph G is a pair (V, E) where V is a finite set and E is a set of 2-element subsets of V The set V is called the vertex set of G and the set E is called the edge set of G Example G = (V, E) where V = {1, 2, A, x, B, a} and E = { {1, A}, {2, x}, {x, a}, {A, B}, {B, 2}, {2, a}}
