thanks ..
plz do remember me in ur prayers i will give u 100% solution
umair sid
thanks i pray and waiting
hera all here is the most easy quiz of the cs502 but remember THERE ARE 3 Question which are asked again in that quiz,..
thanks... remember me in ur prayers...

Back edge is
(u,v) where v is an ancestor of u in the tree page # 128
What algorithm technique is used in the implementation of kruskal solution for the MST?
Greedy Technique page #142
in drsigne G=(V,E) ;G has cycle if and only if
The DFS forest has back edge page # 131
Cross edge is :
(u,v) where u and v are not ancestor or descendent of one another page #129
Forword edge is :
(u,v) where v ia a proper decendent of u in the tree. Page # 129
A digraph is strongly connected under what condition ?
A diagraph is strongly connected if for every pair of vertex u,v e v,u can reach v and vice versa. Page #135
You have an adjective list for G, what is the time complexity to computer graph transpose G^T.?
(V + E ) PAGE # 138
Given an adjacency list for G, it is possible to compute G ^{T} in Θ(V + E) time.
What is the time complexity to extract a vertex from the priority queue in prim’s algorithm ?
O Log (v) page #152
It takes O(log V) to extract a vertex from the priority queue.
There is relationship between number of back edges and number of cycles in DFS
There is no relationship between back edges and number of cycles
Which is true statement in the following
Kruskal's algorithm (choose best non-cycle edge) is better than Prim's (choose best Tree edge) when the graph has relatively few edges.
Dijkstra’s algorithm :
Has greedy approach to compute single source shortest paths to all other vertices page 154
What is the time complexity to extract a vertex from the priority queue in Prim’s algorithm?
O (log V)
Which is true statement
Breadth first search is shortest path algorithm that works on un-weighted graphs
Depth first search is shortest path algorithm that works on un-weighted graphs.
Both of above are true.
Kruskal's algorithm (choose best non-cycle edge) is better than Prim's (choose best tree edge) when the graph has relatively few edges.
True
pleasure rose... do remember me inur prayers plz thx
dears here is the modified quiz of Umair, plz check it for correctness and comment.
CS502 Quiz no# 4 06-07-2012 Solved by Umair sid 100%
Given an adjacency list for G, it is possible to compute G ^{T} in Θ(V + E) time.

There is no relationship between back edges and number of cycles
Kruskal's algorithm (choose best non-cycle edge) is better than Prim's (choose best Tree edge) when the graph has relatively few edges.
Overall time for Kruskal is
Θ(E log E) = Θ(E log V) if the graph is sparse. P-149
True
Has greedy approach to compute single source shortest paths to all other vertices page 154
O (log V)
Breadth first search is shortest path algorithm that works on un-weighted graphs
Depth first search is shortest path algorithm that works on un-weighted graphs.
Both of above are true.
thanks a lot
shukar hay zeeshan ap k face pr bhi smile aayi hay
