Hey now, what's with cutting us 68k-ers out of the picture?

We probably could have 2 divisions...
But then the time limit would need to be destroyed
Actually... 2 divisions, but when showing them they would all need to be run on ti 83+ (for that part) and a certain 68 k calc so that it would be a level playing field in the divisions
If it's in BASIC, the SEs of the z80s are a little faster than the 89 (16MHz to 12MHz, IIRC), so that should compensate for the differences in the BASIC interpreter...

I didn't know the SE was faster than the 89...
Now that i think about it though, the SE is newer (better hardware) , while the 89 has better software efficiency
Apples to Oranges. The 12mhz 68k is slightly better than the 15mhz z80. I really wish that we would see rating in FLOPS, more accurate for cross comparison
I am the eye of the river

The 89 is definitely slower, but then again, what do you expect when the processor has to handle symbolic manipulation vs. straight up arithmetic? 
Only when in Exact mode, cutting to Approx mode cuts down time for complex calculations by quite a bit. Not that you'd need that for Sudoku anyway...

The calculations may be slower, but the processor itself is much more efficient (more FLOPs) than the z80.

So find a more efficient method, or implement the same one in a more efficient way. This won't be a contest if all you have to do is make a big For( loop that checks a matrix.

Lol... I wrote a VERY efficient one yesterday, but i ran it and in the morning i had only half a sudoku (my baterries were low), and my ram cleared... So I will start from scratch again...

OK let me put it this way...
The most efficient method to check for legality in a sudoku puzzle take 1.5-2 seconds to work (on an 83+) . Now 81 checks atleast, so already about 2.5 minutes. Now we know there will be some rechecks after an illegal placement, so that adds a few minutes (getting all 81 areas to fit without any retries is absurd). But then there is going back (or you could handle it other ways... not sure how though) if it discovers that no number can be placed at an area legally. This probably adds the most time.
It probably is possible to get it under ten minutes, but very unlikely. I really want to see how you guys handle the going back part
Oh yeah? I take that challenge. I will write you a working Sudoku generator that can make a puzzle in under 5 minutes by 7pm EST.

Ok... You can probably do it, but still... The fastest is probably around 7+ minutes
ANYWAYS... The clock is ticking...
I am in central time, so better set my clock...
