Graded discussion (GDB) will be launched on 22nd January, 2018 and it will remain open for two days. You can post your comments on the below mentioned topic till 23rd January, 2018.
Consider a very large undirected graph of Email Networks. The nodes (or vertices) represent email addresses, and an edge represents the fact that there was at least one email in at least one direction between the two addresses.
Which technique will you use for representation of the above mentioned Graph in a computer program for its manipulation?
Justify your answer with very well defined and sound reasoning.
A concise, coherent and to the point comment is preferred over lengthy comment having irrelevant details. Your comment must not be more than 4-5 lines. Comments, posted on regular Lesson's MDB or sent through email will NOT be considered in any case. For any queries please email at CS502@vu.edu.pk
Best of Luck!

Whats you guys think about it? correct or not ?
I would use 2 flat tables.
Address (AddressID*, Email)
Connection (Address1*, Address2*)
Address1 will be the ID number that is numerically lower of the pair.
Properties of the given dataset:
1. Could have a large number of nodes.
2. Generally very large and sparce.
3. Requires relatively efficient search algorithm given a node.
4. In general, contains cycles.
Since cycles are present, we can safely eliminate trees. Lists are not useful since the number of branches is not constant. Consider matrix (each column/row is a node, intersection determines edges) but matrices are not space efficient.
Hash tables should provide an efficient storage, as well as rapid searches.
flat tables kahan se aa gae? dekhen... graph represent karne k do methods hain`, adjacency list aur adjacency matrix. in dono main se koi select karna h aur batana h k kyun...
correct or not
It depends on the number of people emailing each other and on the operations done on the graph.
If there is a high chance that 2 people have emailed each other then you should go with adjacency matrix.
On the other hand if the number of edges (2 people who emailed each other at least one) is small compared to the number of email addresses you should go with adjacency list.
Another thing to look at is what types of operations are you doing on the graph.
So, if the majority of the operations consist of querying if two nodes have an edge between them, then adjacency matrix would be the best choice.
On the other hand if the majority of the operations are traversing the graph or querying the list of nodes connected to a given node, then adjacency list would be better.
If you are doing a mix of both types of queries, you could represent the graph as an array of hash tables. So, it would be an adjacency list representation using hash tables instead of lists.
aoa fazal bhai plz gdb comp hogaya ho to share karde
pehly koi gdb samjha do
koi solve sahi bata do
Fazal ur rehman in dono ma sy kisy ak ka lihkna ha dono ni ap ny to dono ko hi mix expalin kia hoa ha
