The final ranking is based on the total number of problems solved. Ties are broken based on the total time consumed.
The total time is the sum of the time consumed for each solved problem.
The time consumed for a solved problem is the time elapsed from the beginning of the contest to the submission of the first accepted run for that problem (in minutes) plus 20 minutes for every other run for that problem before the accepted one. For an unsolved problem no time consumed is computed.
There is no partial credit for any problem
