Clarify the ranking algorithm?
Posted: Fri Apr 24, 2009 4:24 pm
I did an analysis of the output of http://www.hacker.org/challenge/map/get.php and it didn't match up with the ranking shown in http://www.hacker.org/challenge/top.php.
I simply used the "sum of the squares of the difficulty" method to compute my score and that resulted in a considerable smaller score compared to the official ranking.
How do I have to understand the Sentence "The top solver gets 200 points, the next (200 * 0.9), the next (200 * 0.9 * 0.9) and so on"? Who is the top solver? The first one who solved a challenge?
