Null graph,Nn, n=1,2,3,4...,the graph with n vertices and no
edges. (N4=4 vertices with no edges)
4 a) find a graph with 8 vertices with no 3-cycles and no
induced sub graph isomorphic to N4
b)prove that every simple graph with 9 vertices with no 3-cycles
has an induced sub graph isomorphic to N4
Write a complete Java program which takes vertices and edges of
an undirected graph from the input file input.txt (the graph as
adjacency matrix) ,(adjacent vertics of every vertex ),(DFS
traversal of the graph),(BFS traversal of the graph),(Graph is
connected or not connected)
Use the fact that every planar graph with fewer than 12 vertices
has a vertex of degree <= 4 to prove that every planar graph
with than 12 vertices can be 4-colored.
Given an undirected graph G = (V,E),
consisting of n vertices and m edges, with each
edge labeled from the set {0,1}.
Describe and analyze the worst-case time complexity of an
efficient algorithm to find any cycle consisting of edges whose
labels alternate 0,1.
You are given a directed graph G(V,E) with n vertices and m
edges. Let S be the subset of vertices in G that are able to reach
some cycle in G. Design an O(n + m) time algorithm to compute the
set S. You can assume that G is given to you in the adjacency-list
representation.
Assume that in addition to having capacities for edges we have
capacities for vertices, meaning that the incoming flow to a vertex
cannot be more that its capacity. Describe an efficient algorithm to
solve the max-flow problem in such a network.
