Tournament/Marathon List
Binomial-theorem   16
N Nov 13, 2014 by phantranhuongth
PM AIME15/Binomial-Theorem to add your marathon/make any changes to this list

The following list will include Archived Tournaments, Inactive Problem a day Marathons, Active Tournaments, and "running" marathons.

Definition of Archived Tournaments-Tournaments that have a defined end, and have reached that ending spot are defined as archived tournaments.

Definition of Active Problem a day Marathons - The game moderator of the tournament has not set a defined deadline, however, the tournament is dead, and has the results (from the last post of the tournament creator’s scores)

Definition of Inactive Tournament- The game moderator is inactive or few users still compete in the tournament. “Problems of the day” marathons that ended will be included in this list.


Definition of Running Marathons- A marathon where a user asks a question and posts a new question. To be included in this list, the tournament must be mathematical (word marathon, long word marathon, you name it, etc. are not counted), and it must be active (last post in under a month ago and the thread must be on the first page of the forum it is in).

Thanks BT, it's good to see something that organized. But how are you going to keep track of the new marathons that pop up? I think you should wait a few days before adding new marathons to the list just in case it dies off in the early stages.

I'll post an update each week. If a Problem-A-Day thread goes for a while, than ends randomly, I'll put it under the "Inactive Problem A Day" thread. Most of the time, I will PM AIME15 with the new updated list (as he said for me to do in his edit). If you want your tournament to be included in my list PM me/AIME15, and we'll work on including you in the list. Anyways, I see when a new thread pops up, and I'll include it in the list/pm AIME15 to include it in the list.

Just a formatting tip - use hide tags for each section so it doesn't take up so much space.

I don't have time to work on this list anymore (sorry), but I have created a Wikipedia Page on the AoPS Wiki page here. If anyone would be willing to spend some time helping out with formatting, and updating the "Running Tournament" list, that would be greatly appreciated.

Also note, there is no need to send private messages myself about the list, as users can update the above list by themselves.

Thanks for the help and understanding :).
