Re: Trivial O(N^4) algorithm easily passes system tests Do you know a method how to solve it faster??? Re: Trivial O(N^4) algorithm easily passes system tests Послано S.77 6 авг 2011 21:25 My algo is O(N^3). I just read the input matrix row by row and store the maximal sum of subrectangle for each bottom side projection using DP. I did it with 0.015 secs (never did faster). |
