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.

An all-new Arena

Hi All, We are planning a new arena and it is coming but with a twist! Instead of Topcoder working on the arena we are going to fund the community to manage and build out the new version of the arena.

We are going to be launching a CRFP (first draft) (Community Request for Proposal). The goal will be to have the community not only do the dev, but help drive requirements. We are looking forward to getting the community involved.

If interested: Please send your proposals to support@topcoder.com with the subject line: New Arena -CRFP — 'Your TC Handle'

Please use this thread for any queries: http://apps.topcoder.com/forums/?module=Thread&threadID=922202

The entire Topcoder team was saddened to hear of the loss of ltaravilse.

ltaravilse was an integral part of the Topcoder family. He was a member for over 10 years, a member of our Community Advisory Board (CAB), and was a huge help in getting our first TCO Regional event to visit South America.

SRM 735 and TCO18 Round 2C on Tuesday, June 26, 2018 will be run in his honor and will award $5,500 in prizes in honor of ltaravilse. The prizes of $200 will be awarded to best 20 performers in Div-1 and the prizes of $100 will be awarded to best 10 performers in Div-2. $500 will be awarded for TCO18 Round 2C participants. More details to come... All members will be given an option to donate their prizes to the family of ltaravilse.
