A graph G = (V, E) consists of a (finite) set denoted by V, or by V (G) if one wishes to make clear which graph is under consideration, and a collection E, or E (G), of unordered pairs {u, v} of …
WebNow for some more graph terminology. If some edge (u,v) is in graph G, then vertex v is adjacent to vertex u.In a directed graph, edge (u,v) is an out-edge of vertex u and an in-edge of vertex v.In an undirected graph edge (u,v) is incident on vertices u and v.. In Figure 1, vertex y is adjacent to vertex b (but b is not adjacent to y).The edge (b,y) is an out … WebIn graph theory, a vertex cover (sometimes node cover) of a graph is a set of vertices that includes at least one endpoint of every edge of the graph.. In computer science, the problem of finding a minimum vertex cover is a classical optimization problem.It is NP-hard, so it cannot be solved by a polynomial-time algorithm if P ≠ NP.Moreover, it is hard to …

WebHonors Discovery Seminar: Graph Theory, Part II Definition.A graph is planar if we can draw it in the plane without any of the edges crossing. A face of a planar graph is a region bounded by the edges. We say that the region outside a graph is also a face. (For a more senisble version of this: draw your graph on a sphere, and then count the faces.)
