Based on the feedback we received from the July contest we have slightly modified the rules for the August Challenge. This time around we will not be rejudging submissions with new test data. To prevent people from precomputing solutions we will limit the number of submissions to the challenge problem to 20 per calendar day. We will reevaluate after the competition to see if this method has the intended results.
We would like to mention once and hopefully for the last time the guidelines for disqualification:
We reserve the right to ban users based on suspicion of cheating.
We are also happy to announce a weekend long competition at the end of August. Details on this will be announced soon. We are also planning a team based competition for September, this may be judged in the style of ACM-ICPC competitions (time-based, penalities for incorrect submissions). We’ll let you know.
Best of luck!
