CTC Scoring system

The scoring system and formula are exactly same as previous years.

  • Submissions within 60 minutes will be considered for scoring
  • 2 minutes penalty for each wrong submission
  • 15% time penalty for each late day (maximum 2 late days are allowed – so a puzzle can be solved upto 72 hours after it is uploaded)
  • Each puzzle has its own points, which is computed from solving times of top 10% players on that day.
  • Each player gets points for solving a puzzle based on own solving time and others’ solving times. Exponential distribution is used.
  • Total points for a player is sum of puzzle points over 7 weeks.

Just curious -- when there are a lot of people who did not finish the puzzle (as with today's), do they get factored into the calculation for MED?
