by Nick Howe
This really doesn't work very well!
by Nick Howe
2005-11-02 11:55:26 UTC First attempt
by Mike Bindschadler
makes no attempt to optimize row or column sums, but does make a weak attempt to optimize region sums. Only does sligtly better than the example solver

by Niilo Sirola
Some type of relaxation method: first solve the missing elements from the linear system, then try to substitute them with the listed elements.

Just a hack.

Simple swapping -- nothing fancy.

It is, I tested.

by Nick Howe
Actually, not my second attempt, but a revision of FirstStab

Bug fix on Swapster.

Different starting conditions for Swapster.

2005-11-02 15:00:00 UTC Heuristics
by Nick Howe
Trying out some heuristics.
by Nick Howe
2005-11-02 15:05:01 UTC Heuristics 2
by Nick Howe
Added swapping improvement to Heuristics.
by Nick Howe
2005-11-02 15:21:31 UTC Back to the drawing board
by Nick Howe
Revisited solutions in Heuristics 2.

based on POCS
un-optimized.

2005-11-02 15:23:53 UTC look ma, no heuristics!
by Niilo Sirola
(just kidding 'bout the heuristics, of course)

this is my first try, it takes good time but bad score.

2005-11-02 15:28:47 UTC More drawing boards.
by Nick Howe
Added revisions of block regions also.

2005-11-02 15:33:17 UTC Slugger
by Nick Howe
Boy, this is slow.
It keeps searching for improvements until it can't find any.
Code has not been optimized for speed at all.

2005-11-02 15:38:07 UTC Slugger Variant
by Nick Howe
This is like Slugger except it uses the mean instead of the median.
On my test set, it is a little faster but lower quality.
