Posted: Mon Sep 18, 2006 5:09 pm Post subject: XY-Net -- for the fun of it

The following is probably considered to be a Forcing Net or two XY-Chains, but I like to think of it as an XY-Net.

Code:

.....958..8..5..........79........195..7.......63.8........3...6.2.7...1..928.43.

*--------------------------------------------------------------------*
| 1237 12467 1347 | 146 12346 9 | 5 8 346 |
| 9 8 34 G | 46 G 5 7 | 1 26 G 2346 |
| 123 12456 1345 | 8 12346 126 | 7 9 346 |
|----------------------+----------------------+----------------------|
| 23478 247 378 | 456 246 256 | 36 1 9 |
| 5 129 13 B | 7 -1269 126 | 36 4 8 |
|-14 149 6 | 3 149 8 | 2 7 5 |
|----------------------+----------------------+----------------------|
| 1478 1457 -14578 | 156 16 A 3 | 9 26 G 267 |
| 6 3 2 | 9 7 4 | 8 5 1 |
| 17 A 157 9 | 2 8 156 | 4 3 67 P |
*--------------------------------------------------------------------*

B - - -
[r5c3]=1 => [r5c5]&[r6c1]&[r7c3]!=1

B G G G G P A - -
[r5c3]=3,[r2c3]=4,[r2c4]=6,[r2c8]=2,[r7c8]=6, [r7c5]=1 => [r7c3]&[r5c5]!=1
,[r9c9]=7,[r9c1]=1 => [r7c3]&[r6c1]!=1
