Submit problems prepared by you to contest@acm.uva.es and also send a short email to acm@uva.es to notify us about your submission. Read the following paragraph for details:

We are very proud that we have the best programmers of the World registered with our Site. Many of them have helped us on many occasions by supplying solutions, inputs and outputs for different problems and we know that they will continue to do so. But in this section, we don’t ask for the solution of the existing unsolved problems of our volumes. Here we request you to share your thoughts, complex ideas with us by submitting problems prepared by you. You can also submit here the problems of your local contests along with their solutions and inputs/outputs (Also if possible the problem setter’s name). It can be very difficult to arrange a contest on your own but submitting one or two problems may not be that difficult. We will use these problems in our Online Contests mixed with problems of different Regional and Local Contests. Unlike many other contests we shall not hesitate to give you the credit for the problems submitted by you as a problem setter or source (The one that is appropriate). All submitted problems will be considered to be used in Online Contests and may also be added with the Volumes (Note that a problem used in a contest may not be added with the 24-hour Online Judge). The points on which we shall judge a submitted problem are as follows

• The Problem must be Error Free (Looks Error free, we cannot always be certain that a problem is error free).
• The difficulty level of the Problem. It should not be very very easy. But we shall gladly accept very difficult problems :-) (But not unsolved problems :-( ).
• The problem should not contain something that hurts certain rational community. Ofcourse Jokes are allowed.
• Problem statement must be in English.
• The format of the Problem statement must be html, ps or pdf. The most preferable format is html.
• The problem should not be exactly similar to any of the problems in our Volumes. (This point is most important for adding the problem with our 24-hour judge volumes.)
