Graph Theory 101: Directed and Undirected Graphs - Mr. Geek

WebPennsylvania State University WebGraph Theory is an important branch of mathematics. Graphs are mathematical structures which is used for modelling pairwise relationships between objects. In graph theory terms, these objects are called vertices and the relationship two objects is given by edges between them. Graphs are primarily of two types – Directed Graphs or Undirected ... WebGraph theory is a branch of mathematics concerned about how networks can be encoded, and their properties measured. 1. Basic Graph Definition. A graph is a symbolic representation of a network and its connectivity. It implies an abstraction of reality so that it can be simplified as a set of linked nodes. cupa brookfield

Webk-Vertex-Colorings If G = (V, E) is a graph, a k-vertex-coloring of G is a way of assigning colors to the nodes of G, using at most k colors, so that no two nodes of the same color are adjacent. The chromatic number of G, denoted χ(G), is the minimum number of colors needed in any k-coloring of G.
