In this part, we will study the discrete structures that form the basis of formulating many a real-life problem. The two discrete structures that we will cover are graphs and trees. A graph is a set …
For example, the set {2,4,17,23} is the same as the set {17,4,23,2}. To denote membership we use the ∈ symbol, as in 4 ∈ {2,4,17,23}. On the other hand, non-membership is denoted as in …

Introduction to Graphs - CSC 208: Discrete Structures
Consider the following abstract binary relation over universe U = {a,b,c,d,e,f}. R = {(a,b),(b,c),(c,d),(d,e)}. A graph allows us to visualize these relationships. Here is an example …
EECE 320: Discrete Structures & Algorithms Graphs and Trees Some examples with complete solutions 1. Euler’s Theorem states that for any planar graph G= (V;E) with nvertices, eedges …
CS340-Discrete Structures Section 1.4 Page 8 Graph Traversals A graph traversal starts at some vertex v and visits all vertices without visiting any vertex more than once. (We assume …
Use adjacency lists to describe the simple graph given in Figure 1. Solution: Table 1 lists those vertices adjacent to each of the vertices of the graph. Represent the directed graph shown in …
Discrete Structures •We want to solve problems computationally •This requires –modeling the world –devising an algorithm –determining the efficiency and correctness of that algorithm …
Example 1: What are the chromatic numbers of the graphs G and H shown in Figure 1? Solution: The chromatic number of G is at least three, because the vertices a, b, and c must be …
