I am newbee so sorry about the loss in formatting. I'm using firefox/unix for my browser and cut and pasted member Wychwood's post of Nov 14 10:10 am. I can't force the format to be fixed width. Any suggestions on how to do this? (added code tags - Ruud)
- Code: Select all
*--------------------------------------------------*
| 49 6 49 | 7 8 2 | 3 1 5 |
| 15 2 58 | 16 9 3 | 7 68 4 |
| 13 7 38 | 5 16 4 | 29 68 29 |
|----------------+----------------+----------------|
| 34 5 346 | 9 2 168 | 148 7 138 |
| 8 1 2 | 4 3 7 | 5 9 6 |
| 7 9 346 | 168 5 168 | 148 2 138 |
|----------------+----------------+----------------|
| 2 4 7 | 3 16 9 | 168 5 18 |
| 6 3 59 | 128 7 158 | 129 4 29 |
| 59 8 1 | 26 4 56 | 269 3 7 |

But anyway, I got to this point myself but have r8c9 as 129 and not 29. Am i missing a move to force the last reduction or was it a typo? Apart from this i agree with all other cells of Mr/Ms Wychwood's post.
So it would appear that to solve this puzzle we had to use
(1) Some basic reductions
(2) ALS-XY
(3) More basic reductions
(3) XY chain or UR type 1
(4) More basic reductions to complete the solution of the puzzle
All in all a very useful learning experience.
I have written my own s/w to do most of this using the IDL graphics package. Do most of you use some other commercially available package?
