multiple solutions ...

Postby kilted_john » Sun Jul 17, 2005 12:04 am

OK, I just did my first ... yes I am a virgin, but the curious thing was I solved the puzzle, but it did not match the solution that was provided. This leads me to believe you can have multiple solutions as long as you make correct alignments of the numbers.

Anyone else experience this phenomena?? Or did I misinterprept something along the way? Maybe an excel spreadsheat might be helpful ... who knows.

You almost certainly made a mistake. Double check that your solution has each number in each row, column and box.

Here is my solution ...
943 586 721
726 314 589
518 927 634

271 498 356
365 271 498
894 653 217

652 149 873
137 862 945
489 735 162

And here is the solution I was supposed to get ...
943 685 721
726 143 589
518 729 634

271 498 356
365 271 498
894 356 217

652 914 873
137 862 945
489 537 162

It appears that columns 4, 5, & 6 are the differing columns between the two solutions. Some of the rows in those columns have numbers that match, but are in a different order.

Is this wierd or what?? That was why I was wondering if you can have multiple solutions.

Could you please post the starting grid; it is easy to determine if the starting grid has multiple solutions.

... this is what you mean? Zeros represent "empty" cells.
943 080 700
726 103 089
518 000 004

270 000 056
000 201 000
890 000 017

600 000 003
137 802 045
009 030 100

I think I just found where I went wrong ... row3, columns 4 & 6, I changed ... I am such a bad boy.

Thanks for your help ... John

You've messed up with row 2 - it's inconsistent with the starting grid.

... I meant to say row2 and not row3.

Back to the grindstone ... John
