 Posted: Fri May 05, 2006 11:50 pm Post subject: Puzzle Generator Improving |
 |
|
My puzzle generator is slow and still needs improving, but it's not doing bad right now. The following analysis is from Simple Sudoku.
| Code: | 6.1..38...2.7..1..5..1...4....8...15..84.79..24...1....6...9..1..5..4.3...75..2.4
Colors *2
Multi_Colors *4
X-Wing *2
XY-Wing
No Hint |
Which techniques beyond locked candidates (1&2) and naked/hidden single/pair/triple/quad are still needed? TIA! |

Into Sudoku needs:
| Code: | 1x Remote Pair
2x X-Wing
6x Empty Rectangles
1x XY-Wing
3x Dual Imp. Chain |
Sudocue makes use of Finned X-Wing and findes a Jellyfish but as it does not support forcing chains it has to use Guessing to solve it.
edit: SDK-Solve needs X-Wings XY-Wings und some Turbot Fishes to solve it |

1. [r8c1]=8=[r3c5](=2|6=[r3c6]-6-[r2c5|r3c7])(-8-[r3c2])-8-[r2c5](-9-
-[r1c4]=9=[r6c4]-9-[r6c3])=8=[r2c1]=3=[r2c9]-3-[r3c7](=3=
=[r6c7]-3-[r6c3])-7-[r3c2]=(AUR: r34c23)=7|6=[r4c3]-6-[r6c3],
=> r8c1=8.
2. {ATILA(9): r3c3|r6c3|r6c4|r4c5|r3c5|r3c9}, => r3c9=9 and the puzzle is solved.
