To quote an official announcement

We are pleased to announce that the

Fall OMO 2014will be taking place fromOctober 17 to October 28, 2014. You can register a team by following the instructions on our info page. OMO is a team-based contest, and we allow for teams to be up to four people. (Teams of size less than four are welcome too. In fact, every year some brave individuals solo the OMO!)This contest is run completely over the Internet, and therefore, your team can consist of people from all over the world! We already have a team-forming thread in the OMO Forum.

We've created a set of thirty short-answer problems ranging in difficulty from easy to very challenging. Hopefully, you will find these problems to be instructive, elegant, but most importantly, fun to work on.

Cheers, The OMO Team
