* ''The Coding Phase –'' 75 mins'':'' All competitors arewere presented with the same three [[Algorithm|algorithmic]] problems of differentdiffering complexity,. eachEach problem hashad its own maximal number of points. Problem descriptions arewere initially invisible. Competitors havehad 75 minutes to solve these problems. CompetitorA cancompetitor could open any problem description in any order; once hethey opened a problem, the number of points hethey cancould get for the correct solution of that problem startsstarted decreasing over time. When the competitor submitssubmitted the problem solution (asolution—a code that successfully compiles), hecompiles—they iswere awarded with the current amountnumber of points hethey cancould get for that problem. HeThey cancould re-submit a solution, getting the further descreasedecrease amountnumber of points, minus extra penalty for the resubmission. During thethis coding phase, competitors cancould see the current points awarded to each participant, but they don'tcould knownot see whether the solutions of those participants arewere correct or wrongincorrect, thusincluding whether these scores willwould hold after ''The System Testing Phase'', or willif they would be reset.
* ''The Challenge Phase'' – 15 mins: Each competitor cancould see all submissionsubmissions donecompleted by the other competitors. HeThey cancould (optionally) challenge any of them, by submitting [[Test case (software)|test cases]] that willwould cause other competitor's submission to produce aan wrongincorrect result. Submission of a correct challenge test case givesgave sumitterthe submitter a 50 points award, but submission of an incorrect test case (i.e. the challenged solution can solve it successfully) willwould lead to 25 points penalty for the test case submitter.
* ''The System Testing Phase'' – In the last phase, system tests arewere automatically executed for all of the submissions from all competitors. If a submission failsfailed testing, the scores awarded for that submission during ''The Coding Phase'' arewere reset to zero. The final scores after the system testing determinedetermined the winner.
