Finding the largest sub vector in a sequence

neonic75 · 2009-09-14 10:52:42

Hi folks, I need to find the largest sub-vector from a sequence of integers, both positive and negative. For example: 6,94,-63,-41,20,5,-61,83,-14,-50, 36,30,32,51,96,72,99,23,-59,-23, The largest sub vector here is 6,94,-63,-41,20,5,-61,83,-14,-50, 36,30,32,51,96,72,99,23,-59,-23, Any ideas? Is there an algorithim that…

Hi folks,
I need to find the largest sub-vector from a sequence of integers, both positive and negative. For example:

6,94,-63,-41,20,5,-61,83,-14,-50,
36,30,32,51,96,72,99,23,-59,-23,
The largest sub vector here is
6,94,-63,-41,20,5,-61,83,-14,-50,
36,30,32,51,96,72,99,23,-59,-23,

Any ideas?
Is there an algorithim that will do this?
Cheers

This is called the largest subsequence problem. There is stuff on it here and here. Both these seem to use dynamic programming.
