- rank (The rank of the person on the problem of the week by language)
- same_rank_nb (The number of people with the same number of bytes)
- total (Total number of people who participated in the challenge in the given language)
- multiplier (multiplier is a coefficient that multiplies the first solution by its value under certain conditions)
Multiplier: min( max( exp( ( total / same_rank_nb ) / 70 ) / 6 + 0.8 , 1 ) , 3) if rank == 1, else 1
Score: round( ( 1 + log10(total) / 6 ) * ( total - rank + 1) / ( total ) * 1000 * multiplier )
- total (Total number of people who participated in the challenge in the given language)
- before_bytes_nb (The number of bytes before the upgrade)
- new_bytes_nb (The number of bytes after the upgrade)
- diff = before_bytes_nb - new_bytes_nb
Score: log5( (diff>100?100:diff) + 10) * 3600 * log( 1 + (float)total / 100 );
If there are two improvements like for example: 100 -> 90 then 90 -> 80 by the same user, it will be counted as 100 -> 80
