CHP-7 GRAPH

CHP-7 GRAPH. INTRODUCTION. A graph is a special types of another important non-linear data structure called graph. It differ from tree in the sense that it represents the relationship that is not necessary hierarchical in nature, that is node may have more than one parent.

V 1

V 1. V 2. No edges between vertices in V 1 or V 2 This is a bipartite graph but not a complete bipartite graph ( so it is NOT K 6, 4 ). b. a. c. g. f. e. d. {a, b, d }, {c, e, f, g} K 3, 4. How many vertices and edges in K m, n ?. If a is in V1, then, b, d, e must be in V2 (why?)

Graphs

Graphs. It's a world-wide webby wonderland. Why?. Graphs are often used to represent real-world information and real-world structures. Graph Theory was even invented to solve a real-world problem.

Graphs

Graphs. CSC 220 Data Structure. Introduction. One of the Most versatile data structures like trees. Terminology Nodes in trees are vertices in graphs. Lines connecting vertices are edges . Each edge is bounded by two vertices at its ends.

GRAPH

GRAPH. Graph. A graph G = ( V ,E) is composed of: V : set of vertices E : set of edges connecting the vertices in V An edge e = (u,v) is a pair of vertices Example:. a. b. V = {a,b,c,d,e} E = {(a,b),(a,c),(a,d), (b,e),(c,d),(c,e), (d,e)}. c. e. d. Types.

The Grammar According to West

The Grammar According to West. By D.B. West. 5. Expressions as units. There exists i < j with x i = x j . ( Double-Duty Definition of i, not OK ). There exists i such that i < j and x i = x j. The number of nonneighbors is n-1-d(u) ? i.

Graph Coloring

Graph Coloring. March 25, 2004 CS 146 (1:30 pm-2:45 pm) by Park, Jong Seok. Definition. A coloring of a simple graph is the assignment of a color to each vertex of the graph so that no two adjacent vertices are assigned the same color. Chromatic Number.
