Graph Representation
The two main graph representations we use when talking about graph problems are the adjacency
list and the adjacency matrix. Its important to understand the tradeof

An O(jV j2) Algorithm for Single Connectedness
Samir Khuller
Abstract
A directed graph = ( ) is said to be singly connected if
implies that there is at
most one simple path from to for all vertices
2 . In this paper we design an algorithm
to test a graph

CSE 5311 Homework 4 Solution
Problem 22.1-7
The incidence matrix of a directed graph G = (V, E) with no self-loops is a
|V | |E| matrix B = (bij ) such that
1, if edge j leaves vertex i,
bij = 1,
if edge j enter vertex i,
0,
otherwise.
Describe what the e

Show the d and pi values that result from running breadth-first search on the directed
graph of Figure 22.2(a), using vertex 3 as the source.
After running a breadth first search on the graph, the foll
