Online Math Open

Hi Everyone,

I'm delighted to announce that registration is now open for the Fall 2013 Online Math Open! Thank you all for your patience.

For those of you that don't already know, the Online Math Open (OMO) is a team-based contest, where teams of up to four students are given over a week to solve 30 short-answer problems. The contest is completely free, and takes place over the Internet -- therefore, students may team up with anyone they like around the world.

This year's contest will take place from October 18 through October 29, 2013.

Starting this year, the contest itself will be hosted on internetolympiad.org. Team captains can register a team of up to four students there by clicking the link labeled "Register/Update Team". Note that, in particular, only the team captain needs to register on the website. For more information, please check the information page on our website.

We work extremely hard to ensure our questions are of the highest quality, so that even the easy problems will be interesting, non-routine, and not "just another contest problem". (You can see some of our previous problems, including discussion, in the contest section of AoPS .) We hope you enjoy this year's problems as well!

Best, The OMO Team

Hello all,

If anybody would like me to facilitate e-introductions between any of you, so you can coordinate OMO participation with people you only know via Brilliant, then let me know.

Instead of posting email addresses publicly here, just contact me at discussions@brilliant.org if you would like to contact someone. I will check with both parties, and then email you the contacts of people who want to be on a team with you.

Have fun! Peter Taylor Staff · 3 years, 10 months ago

Two questions that arise for me: 1) Is there an age-restriction on the participants? 2) How does the Team enforce the prohibition of graphing tools and such? Ton De Moree · 3 years, 10 months ago

Log in to reply

@Ton De Moree There is an age-restriction. It says he mustn't graduate from high school Zi Song Yeoh · 3 years, 10 months ago

@Zi Song Yeoh Thank you! I missed that :) Ton De Moree · 3 years, 10 months ago

Log in to reply

@Ton De Moree There is no way I think they can enforce the prohibition of graphic tools and such. I have graduated from school and won't be eligible for the competition. But I am participating just for fun. Would you like to team up with me, Sir? Lokesh Sharma · 3 years, 10 months ago

Log in to reply

@Lokesh Sharma I can't predict how much time I will have, but I would like to participate for fun as well :) Let's team up :) Ton De Moree · 3 years, 10 months ago

Log in to reply

@Lokesh Sharma Did you register a team yet?

I've had contact with the organisation and it should be no problem to participate off the record. Just add '(off-record)'in the team name.

I can ask a friend of mine to join in as well :) Ton De Moree · 3 years, 10 months ago

Log in to reply

@Ton De Moree That's a good news. What should be the name of our team?

For now, I have registered with name 'ICE(off record)'; it can be changed anytime.

Sure, ask your friend to join as well. It would be nice. Lokesh Sharma · 3 years, 10 months ago

Log in to reply

@Lokesh Sharma Is ICE short for something? It's as good as anything I can come up with :p.

Should you need to contact me, my email is listed on my profile page :) Ton De Moree · 3 years, 10 months ago

Four members are not a requirement; I believe there have been teams in the past with only one person. Obviously, however, he is at a clear disadvantage. Akshaj Kadaveru · 3 years, 10 months ago

sorry, but could you please specify the requirements for registering contest? Kanasfi Kanasfi · 3 years, 10 months ago

@Kanasfi Kanasfi Registration information and rules are here: http://internetolympiad.org/pages/14-omo_info Teams of up to 4 students should register under the account of one team captain. Michael Kural · 3 years, 10 months ago

Let me see if I understood correctly: During the competition i can enter as many times as i want to the web page and see the problems? I mean, if I open problem number one, that doesn't means that i'm forced to answer it at that specific moment, right? Diego E. Nazario Ojeda · 3 years, 10 months ago

Log in to reply

@Diego E. Nazario Ojeda You receive all problems at the beginning of the competition. You can submit any answers as many times as you want during the week, and your most recent submissions for each problem are graded at the end of the competition. No feedback about whether your answer is right will be provided until the submission period is over. Michael Kural · 3 years, 10 months ago
