A very useful link ,list indept analysis of basic to advanced algorithm ,many which are listed above ,very helpful read http://emaxx.ru/algo/ though in russian but google translator might help. :) answered 27 Jul '13, 03:48

Edit: It would be a nice idea to group these algorithms. For example, KMP algortihm, AhoCorasick algorithm, RabinKarp algorithm all fall under the category of String Match, and hence should be put under the category of string match algorithms; and so on for other algorithms as well. Grouping would help newbies like me to explore a particular group and learn all the algorithms in that. answered 24 Jul '13, 13:45

Hello, I can add a few more topics:
Sadly, this list is endless and the hardest part is to understand which of these topics need to be applied to solve a given problem. As a bonus, you can have variations of these standard topics which may require mixing some of these concepts. I will edit the above post with all these suggestions, except some of the suggestions given by @n2n_, since putting on the same bag, FFT and Sieve of Eratosthenes for finding primes, seems a bit overkill to me, as the second one is a basic algorithm and not needed to advanced problems I would say :) Best regards, Bruno answered 24 Jul '13, 14:23

Hello @all and especially @admin, Is the idea of linking all of the above topics to some resource with a tutorial and suggested problems still up? Because if it is, I can try to write about the topic 3. Fast Modulo Multiplication (Exponential Squaring), as it is a topic I master relatively well, and, when I'm finished with my tutorial I can provide the link here :D What do you think? Best regards, Bruno answered 12 Aug '13, 16:39

Great job!

We still have much more to do :D And me, personally, I have way much more to learn :p

This website can also of great help in learning basic algorithms: http://www.learnalgorithms.in/ answered 14 Aug '13, 10:37

I'd suggest further adding

> Catalan numbers Why? This is not an algorithm. The way they can describe a lot of stuff is nice, but I've never ever seen them used in a solution in competitive programming (unless you count "bruteforce the first few numbers and google them in OEIS" an algorithm, which I don't). Similarly, anything that contains "adhoc" is not an algorithm, practically by definition. "Adhoc" means something that doesn't fall under a wellknown algorithmic technique. answered 24 Oct '14, 05:19

Being a beginner and a little weak at Data Structures particularly from where should I start to get a good grip eventually? answered 26 Oct '15, 03:45

There is an "awesome" resource for this and a lot other things. https://github.com/sindresorhus/awesome Though I don't remember the original author's name, this is the best I've come across. Be sure to check it out. answered 26 Oct '15, 13:51

You can also add data structures as DS + Algo's = Programs. I suggest adding a few basic data structures which would help. Also you could add topics like DP. answered 30 Nov '16, 12:38

Can anyone also mention the approaches that we have to know like Dynamic Programming or any other approaches for programming contests. Classifying these algorithms based on the approach will also really be beneficial, may be i am asking for more here :). answered 13 Apr, 17:43

Hey guys have a look at this blog :::: Important Data Structures and Algorithms answered 07 Jun, 07:23

You can refer to this link. http://www.geeksforgeeks.org/fundamentalsofalgorithms/ answered 07 Jun, 11:32

It will be great if we can build on this to give links of useful resources against each algorithm and also mention problems which require these algorithms to be solved.
@admin nice thought...it will be very very helpful :)
@admin: Great suggestion. Will do when I have time ;)
Should we make this as a community wiki and people can keep adding and editing it there? The down side is that the votes that you have gathers will be lost. Or we can create another community wiki with the contents of this thread and the community can edit it there. What say?
@admin: Please do, I don't mind those votes as long as it will help the community ;).
@admin: Although many of the things listed above are covered in society like Topcoder, codeforce as well there are content available at the internet too. The more detail list is available at (http://www.codechef.com/gettingstarted > List of Topics for programming Competitions). Again if the things are missing and we have better solutions, we can write it under the tutorial section in codechef.
I have added link to my tutorial about point 3 on the original post... If you find it good enough feel free to add it to codechef for schools page as well! It would be an honor :D
Added link to point 12 :)
I'm bringing this back up to let you all know that I will use my own problem, MARBLESGF to write a tutorial on BIT/Fenwick Trees :) I will post it when its complete and also provide link here :D
Awesome compilation of all stuff in one place, appreciate everyone's hardwork :)
