I agree, less is more. Java is a dead language, like French.
Now what? You ask for more languages and now it's too many? You guys are too confusing :mad: :D If there are only 1 or 2 entries it's sort of unfair to get a winner, but... I don't know... We'll see...
There's only 1 last thing to take care of before the contest starts eyeRmonkey, shouldn't be long. Sorry for the delay :)
No problem. Like I said I have no idea what I'm doing, but I'm excited anyway. :)
Alright, get started everyone :)

You didn't mention if the puzzles will always be in 9x9 format. That was my biggest question before I started making mine.
I actually wasn't aware that there were sudokus other than the 9x9 ones... So I guess 9x9? What else is there?
In the wikipedia article is says they can be any size. Glad to hear though, that will save me a lot of time of checking LBounds UBounds, I can just hard code it for 1 to 9. Thanks.
try the 16 x 16 variety. It'll keep your brain fried for a while :)
Samurai Sudoku its a wierd shape. Google for it.
That would be hard to code!!!!
Manavo, i only asked that C# be added not these stupid PHP, Delphi and JAVA (WTH are you guys thinking?)
I have a good program for solvıng sudokus: ıt ıs known as a 'braın' and ıs very useful for doıng eleventy bıllıon calculatıons a lıfetıme.
P.S. There are no dots on my 'ı's because ım on holıday ın turkey wıth a dıfferent layout. There ıs no dotted ı key.
Wossy, they weren't added ;)

Monkey!
Why have you come to that conclusion?
What puzzles you about this puzzle?
:wave:
-Lou
Well, I managed to solve one pretty easy one, but still haven't gotten a system figured out. I'll try a few more tomorrow, as I'll be offline for most of the day.
Hopefully I can come up with a method to solve them.
it's easy. You can only use numbers. :)
What???
Now you tell us.
So hows this thing going? I gave up a while ago. Is anyone working on theirs?
There is the thread discussion thread in the contest section and another thread in the games section that there is discussion about it... Why did you give up? :(
Oh, sorry, I didn't know there were any other threads.
I gave up because I couldn't solve one by hand, so there is no way I could make a program for it.
Ah, come on, try! There are still 3 weeks to go :D
Ohh, darn!Quote:

Here's some more you can try!

Build a list of all the values a cell could be.
Then, for each revealed cell, delete all of that cells could be's, then place in it its must be.
Then, for every cell in that mustbe's row, delete that must be from each of those cells,
Ditto per column,
Ditto for the actual 3x3 parent SQUARE.
Then, look for pairs of identical COULD BE numbers, per row, column, or SQUARE
If you find 2 cells with 2 COULD BE's, and they are the same COULD BE's, then those values cannot be anywhere else in the group your checking. Delete those values everywhere else in the group that they're in.
Look at each cell whose COULD BE count > 1.
For each value, check and see if that COULD_BE value is anywhere else in the group you are checking.
If it's not, then that cell MUST BE that number.
{Group = Row, Column, 3x3 SQUARE}
with just those three rules, you'll find you'll be able to solve some of the puzzles, AND it'll get you started thinking up more rules to include in your solver.
:wave:
-Lou
Just to mention that is what I haven't even done all that in my solver and it solves all the easy ones :) So get started monkey :D
Manavo,
Haver you tried my newest set?
Specifically, the ones whose "difficulty" level >= 8? (The number in the solution set that corresponds to the _XXXX_ in the msk set}

sample (4 easy, 4 medium, 4 hard)

can somebody give me more puzzles to check.. i really love number puzzles nevermind the program. :wave:
uhmm Lou, solution set meaning there can be many solutions to a sudoku puzzle? I was pretty sure that it has only one solution.. well that's what I deduced from solving some puzzles. :(Quote:

Therefore, if the puzzle has more than one solution it is not a sudoku puzzle.... I rather like those original sudoku puzzle they have a form and they are written by hand...Quote:

Lou, haven't had a chance yet... I can't seem to think how I can incorporate the things that go through my head when I'm solving them by hand into code... But I will soon, I promise :)
oceanebelle, we don't have some predetermined puzzles that we are going to use, when marking time comes along we'll find some and test the entries with the puzzles we choose.
monkey, get working ;)
if i could do this in Haskell it would be infinitely easier than vb/c#.
I don't get that part. I did the other 2 parts though and thats working well (on the MOST simpe puzzels with only a few squares missing).Quote:

And Yes. I endeaver to submit ony puzzles with one and only one solution.
No one has yet reported I've done otherwise.

I also refer to that as each cell could be 9 values.
Or... each cell has 9 COULD_BE's.
Now, lets say you KNOW the value of 1 cell, thru the initial settings of a puzzle, or by progressive elimination.
THEN, for every row, column, or SQUARE {3x3}, that value is removed from each of its groups, thus you are eliminating 1 COULD_BE from that cells row, column, and SQUARE, wherever that value exists.
SO... Your cells all eventually decrease in the number of possibilities that they COULD_BE, from their initial nine, to something lower.
Eventually, {hopefully}, you will have cells that might be, or COULD_BE, 2 and only 2 values. Therefore, I just say, they have 2 COULD_BE's.
So,
lets say you have a row where 2 cells COULD_BE 1 or 5, simultaneously.
For some reason, other cells in that row still have marked 2 or 5 as possible candidates, along with other numbers. Since 2 cells, well, MUST_BE a 2 or a 5, then the numbers 2 and 5 MUST BE ELIMINATED from every other cell in that row.
Ditto same thing, except columns for rows, ditto same thing, except 3x3 SQUARES for rows.
:wave:
-Lou
OOPS!
I just saw that you've highlighted 2 rules, not one.
Ok.
Lets say, after successive elimination by established rules, in your group, you've got 9 cells. each cell COULD_BE some set of numbers, 1 thru 9. After inspecting each cell, you might notice, one cell COULD_BE 1,2,3, or 4.
Comparing that cell with all the other cells in its group, you might notice that no other cell has "1" for a could_be. Guess Where the 1 must be!
Thats right!
:wave:
Thanks for the help so far Lou. I understand all the rules you posted and am workin on ways to apply them. :thumb:
