These are the official SPOJ standings. Please note that the formulae used for calculating the scores are currently evolving. At present points are awarded to each user as follows:

  • for solving classical problem p: 80/(40+number_of_people_who_have_solved p) points
  • for a top score in any challenge: 3 points,
  • for any lower score in a challenge: (user's_score relative_to_the top_score) points.

Numbers given in brackets beside the scores correspond to the number of solved classical problems and the number of challenges for which the user's best score is also the top score, respectively.

All feedback concerning the methods used for generating statistics is most welcome. Please post remarks in the forum, or mail them directly to our contact address.
