Das Gitterpunkt Problem



Overview: This was a project I did in the Spring of 2001 to learn backtrack enumeration techniques. It is a Ramsey problem. The table can be interpreted as the minimum number of integer vectors in k dimensions so that there must exist an n-set of points that average to zero.

Results:
Points/Dimension 1 2 3 4 5 6
1 Point 0 0 0 0 0 0
2 Points 2 4 8 16 32 64
3 Points 4 8 18 40 76 140
4 Points 6 12 24 48 96 192
5 Points 8 16 36 73 149 256
6 Points 10 20 40 80 160 320
7 Points 12 24 54 106 192 384
8 Points 14 28 56 112 224 448
9 Points 16 32 64 128 256 512
All entrys without a link are of the form {0,1}^* x (Dimension-1).
