With my current program they are rated 27, 19 and 25* points, where the * after 25 means, that the first time my program had a grid, where no candidate could be eliminated with subnets under the constraint, that only possible eliminations were used (both for nets and there subnets), that would bring a progress of at least 3 candidates (in other words, when you eliminate the number and continue with basics, at least 2 more numbers can be eliminated). So the limit was lowered to a progress of 2, what means, that the calculation is much deeper and needs about 3 times longer.

This is the grid:

- Code: Select all
`*--------------------------------------------------------------------*`

| 12679 2579 3 | 4 257 157 | 567 8 569 |

| 1467 4578 1568 | 137 3578 9 | 2 567 34 |

| 2479 245789 2589 | 237 6 3578 | 34 579 1 |

|----------------------+----------------------+----------------------|

| 2349 23489 7 | 369 1 45 | 3568 2569 235689 |

| 1349 6 189 | 379 45 2 | 13578 1579 3589 |

| 5 239 129 | 8 379 367 | 1367 4 2369 |

|----------------------+----------------------+----------------------|

| 2367 1 256 | 2367 23478 34678 | 9 256 24568 |

| 8 2579 2569 | 12679 2479 1467 | 1456 3 2456 |

| 2369 239 4 | 5 2389 1368 | 168 126 7 |

I calculated over 2000 solutions (in more than 2 hours!), that only differ in the last 5 steps. This is the first one:

- Code: Select all
`r1c1<>6(r7c8<>2,r6c7<>1,r1c2<>2),r7c9<>6,r9c8<>1(r8c2<>5,r5c8<>5,r7c9<>8,r4c8<>6,r2c3<>6,r1c1<>1),`

r4c8<>6,r1c6<>1,r2c5<>3,r7c8<>5,r1c2<>9,r4c4<>6,r1c6<>5

How should i rate that ? My first thought is 5 extra points, but when i add other techniques, this situation probably will not arise and a better comparison is possible.

So these are the top 3 in the moment:

- Code: Select all
`dml 3/07: 30 points, ER 10.8`

Concerning the gsf rating, i was not aware of this kind of output for puzzles, that could not be rated (i saw the same now, when i scanned Ocean's puzzles), an older version wrote out "no solution". Maybe others can help you with the options.

Anyway, it seems that all your (and others') puzzles with a rating of 0 as the second number are non-rated.

If you have thousands of them, in the moment i would need a month to get a rating (I thought i would be safe with my performance for a while, because those puzzles are really hard to find).

But it would be nice, if you could post say 50 of them, this would help me to improve my program.
