You will receive one point for solving a problem (passing all test cases - no partial credit), regardless of the level of difficulty of that problem.
You can submit solutions as many times as you'd like, there are no penalties for incorrect submissions.
Each contest will have one min/max tie breaker problem, where the best solution will receive one point and all other solutions will receive a fraction based how close they come to the best solution.
01:15 AM, 10th November, 2010 (IST) : Based on your feedback, for the problem GRAPHCH, we are planning to rejudge the last submission for every user on new test data. Will update you guys more about the exact scoring rules by tomorrow. Thanks for your patience.
05:06 AM, 10th November, 2010 (IST) : The following clarification has been added on GRIDCHEF:
For this problem, a path is any sequence of cells, such that the first cell is the same as the last cell, no cell except the first/last cell appears more than once in the sequence, and adjacent cells in the sequence are adjacent in the grid.
11:55 PM, 10th November, 2010 (IST) : For the problem GRAPHCH, we will re-judge only the last accepted submission on new Test Data. We will extend the time limit on the new data to try and ensure that the accepted solution does not time out.
