@admin : I think scores on Feb’14 challenge leaderboard consists of added scores of both the challenge problems LMATRIX and LMATRIX2. Please clarify!
Please read this announcement on the contest page :
10/02/2014, 03:00 IST : We have added another problem LMATRIX2 in place of LMATRIX. The submissions to LMATRIX have been stopped. The submissions made towards solving LMATRIX will not be considered in the contest.
The ranks will be adjusted in a few days to not reflect the submissions made to LMATRIX.
Yeah, read that after posting!
