Last year we had launched a problem writing Trip to 2019 TCO Finals. However, after feedback from the community and writers particularly, we have decided to increase the number of trips and also make it simple for you to earn a trip. We now have 5 trips to 2019 TCO Finals and 5 Trips to 2019 TCO Regional Events.

With 100 points, you can win a trip to the 2019 TCO Finals (location to be revealed later in the year)and with 65 points you can win a trip the nearest regional to your location.

You can submit your problems and earn points during any stage of TCO. All problems must be submitted correctly via the process explained here by midnight (12:00 am) Eastern time on the final day

Points

Point Allocation Easy Medium Hard
SRM Div 2 2 3 5
SRM Div 1 5 10 20

Trips

Trips* Number of Trips Points Required
TCO19 Finals Trip 5^ 100
TCO19 Regional Trip^^ 5 65

^Trips will be awarded on First Come First Serve basis.

^^The Regional Trip will be awarded as a one-time reimbursement of a max of $500 for members travel and other logistics.*

Points Bucket The points will work as a points bucket to make you earn trips. Which means, in case you earn 165 points, you can use them for 1 TCO Finals Trip and 1 TCO Regional Trip. Note: A member is only entitled to win 1 trip to TCO19 Finals and 1 Trip to TCO19 Regional Event.

Standard TCO eligibility also applies.

Check out the current standings

How to submit your problems

Please visit this page for more information on how to submit your problems through our system. It’s important to note that you will be communicating via email to us at talgorithm@topcoder.com in addition to using the system to submit. Please be sure to communicate in a timely manner so you can earn your points! Good luck!

Good News — No More Java Security Issues with Topcoder Applet: While we are working on the new arena, we are also trying to reduce the issues you face with the Topcoder Java Applet. With the new version of the Topcoder Java Applet, you don'€™t have to add anything in Java Security Exceptions.

We have also revamped the Problem Writer Trip for 2019 TCO Finals. Easier and More trips. Learn More

New Version: http://www.topcoder.com/contest/arena/ContestAppletProd7.2.jnlp

To Participate in your first Topcoder Contest:

  1. Install JDK add Java set environment variables to point to JDK binaries
  2. Download and Run the new Java Applet (Right Click and Open)
  3. Topcoder Contests are a little different — you need to look at the Definition section as this section will tell you how the class needs to be declared and the method name.

So in this example, if we were coding in C++ we would declare something like what you see below.

class RingLex {
  public:
    string getmin(string s) {
      string ret = "";
      // code your solution for the problem here
      return ret;
    }
}

Note that our class name and method name match the definition values shown above, and case matters. It's very important to get this exactly right, otherwise, your solution will fail!

Topcoder SRM 745 is scheduled to start at 21:00 UTC -5, December 27, 2018. Registration is now open for the SRM in the Web Arena or Applet and will close 5 minutes before the match begins.

For this contest, we are running it as an experimental "fun" SRM, using a bit different format than usual. The 75 minutes of coding, 5-minute intermission, and 15-minute challenge phase will remain the same. However, instead of two separate divisions with three problems each, all competitors will be in a single division, facing the same set of six problems.

The match will be unrated and won't be used for TCO19 Stage 2 Algorithm Point Calculation.
