Should I also learn advanced mathematics?

Short answer: no.
Longer answer:
Yes, it is:
1. get the input
2. produce an output
raghav singh wrote:About algorithms, how many are known?
Should I learn all of them. Or it is an infinite list.

Paweł Baczyński wrote:No problem.
I think that there is no general universal algorithm.
The only things various algorithms have in common is that they require some data, they process it and return some result.
This could be listed in two steps as I did.
And those two steps can be considered an algorithm itself

Wirth's Algorithm and Data Structures is still of interest (and freely available as PDF), and (somewhat newer) Cormen/Leiserson/Rivest's Introduction to Algorithms is not bad.

No more Blub for me, thank you, Vicar.

There's still time to join the free online course in Algorithmic Thinking from Coursera, which just started on Monday.
Several JavaRanchers seem to be following the course  http://www.coderanch.com/t/638573/BunkhouseLounge/OnlineAlgorithmicThinkingRiceUniversity

Those are excellent (I haven't done Algorithmic Thinking, so I can't comment). And the examples and assignments are in Java, which is an advantage if that's what you're familiar with.
There are only two hard things in computer science: cache invalidation, naming things, and offbyone errors
