A: CR Community Goes to GitHub!

syb0rgI have some points to make on this subject: How the Code Review Community is going to use GitHub is still being debated and decided. If you want to be part of that process, I recommend you join the "The 2nd Monitor" (Code Review's chatroom). This is not aimed to take you away from the Code Rev...

Okay, who invented cliffhangers in TV-series!?? "¤/(@$€)?£~@(~!

Q: Sudoku Solver in C

syb0rgI had this code lying around, so I figured I would submit this as my first attempt at a weekend-challenge. I would prefer if reviews contained suggestions on how to improve the algorithm, but all suggestions are acceptable. #include <stdio.h> int isAvailable(int puzzle[][9], int row, int col, ...

Only two answers now.

Ah, I see.

@syb0rg did the answer give you any good advice? do you want it back?

No one besides me that has seen the POI TV-series? People, people, people... you don't know what you're missing... :)

Malachi
@syb0rg like was it a good answer for the most part?
@syb0rg he had like 5 upvotes.
 
syb0rg
syb0rg
@Malachi There was one good point in there about using some fast int instead of a normal int because I was using only unsigned values, but that was about it.
 
Malachi
Malachi
I thought that I could vote to undelete, but I can't do that yet I guess.
@syb0rg I would have voted to undelete he lost out on like 46 rep points

@Malachi I didn't ask him to delete it, that was his own decision. He does get a badge for it though.
 
Malachi
Malachi
@syb0rg I was thinking of flagging it for undeletion. I think I can do that.
 
syb0rg
syb0rg
@Malachi The point about int_fast8_t was good, but everything else wasn't very useful (some of it being from other answers). Is it worth the trouble?
 
Jamal
Jamal
If he deleted himself, I assume it's a personal decision.
 
Malachi
Malachi
if it was of more value I would have flagged it, but from what you are saying it isn't worth keeping around. @Jamal @syb0rg
@syb0rg your Diagonals have duplicate numbers BTW

syb0rg
@Malachi Where?

Q: Need Help Optimizing PHP/MySQL Code Snippet

Dizzy49I am sorry for the simple request, but I'm trying to figure out the best way to optimizing the following bit of code. I hate using 20 lines of code when 12-15 will suffice. I also don't like having to use intermediate variables if I don't need to. $total_query_raw = "SELECT SUM( total ) AS tot...

@syb0rg from top left corner to bottom right corner it repeats 9's and 2's
 
Jamal

Again, it's a personal decision. If you think it's worth it, I can super-ping him. As a moderator, I should mostly deal with answers that go against the site policy, which this one does not.
 
syb0rg
syb0rg
@Malachi Does that conflict with the rules of Sudoku?
 
Malachi
Malachi
@syb0rg no I was messing with you.
 
syb0rg
syb0rg
@Malachi You had me worried for a second.
My (deficient) robot-half was going haywire there.

10:50 PM
@syb0rg that would make the game interesting though, wouldn't it? I wonder if it is possible to solve one like that.
I suppose if you did
1,2,3,4,5,6,7,8,9
2,3,4,5,6,7,8,9,1
3,4,5,6,7,8,9,1,2
...
that wouldn't work either
 
syb0rg
syb0rg
@Malachi Nope, haha.
 
Malachi
Malachi
that is going to bug me.
back to work
 
syb0rg
syb0rg
Do you have a Github account @Malachi
 
Malachi
Malachi
@syb0rg I might have one, but I don't remember the credentials for it, or maybe it's a Gist that I have....IDK
I may set one up tonight if I get on my computer at all. I need to order a Keyboard for my other laptop too

@Malachi Give me a little while with my C# code and I'll see if I can solve a Sudoku that has to have unique diagonals as well, I'm quite sure that it's possible.
 
Malachi

11:01 PM
I know it's possible but I don't think there are going to be very many puzzles. you know what I mean @SimonAndréForsberg
I just got Defender of the Realm
 
Simon André Forsberg
Simon André Forsberg
@Malachi Yeah that's true. It won't be as many puzzles as there are now. I don't plan on exactly counting them either.
 
Malachi
Malachi
@SimonAndréForsberg Sissy....... JK
 
Simon André Forsberg
Simon André Forsberg
@Malachi Sorry, just think there are better things to do than to count Sudokus
 
Malachi
Malachi
@SimonAndréForsberg I was just messing with you, but you could have the application do the counting.
 
Simon André Forsberg
Simon André Forsberg
@Malachi Yes, but it would do the work for a very long time. Counting possibilities by brute-force isn't exactly the most efficient method
@Malachi Related:
 
Malachi
Malachi
11:05 PM
@SimonAndréForsberg but there is a pattern, so there must be a quicker way to do it than brute force. you probably only have to do 3x3 cubes or something like that.

There are a total of 6.7*10^21 of Sudoku grids

Malachi
@SimonAndréForsberg ^^ worthy of a star
 
Simon André Forsberg
Simon André Forsberg
See the video I linked for more mathematical info about Sudoku. THAT video deservers the star :)
 
Malachi
Malachi
@SimonAndréForsberg I am watching it
swap the 3's with the 5's and it's valid??? holy crap
 
Simon André Forsberg
Simon André Forsberg
@Malachi yeah, if you swap all the 3s with all the 5s, it's still a valid grid.
 
Malachi
Malachi
11:18 PM
@SimonAndréForsberg what about 3's and 4's
 
Simon André Forsberg
Simon André Forsberg
@Malachi Lol, yeah of course you can swap those too
 
Malachi

@SimonAndréForsberg look what you went and did.
 
Simon André Forsberg
Simon André Forsberg
@Malachi I made you start looking at Numberphile?
 
Malachi
Malachi
@SimonAndréForsberg I have watched several of them before, but I get hooked when I am supposed to be doing other things.
 
Simon André Forsberg
Simon André Forsberg
haha :)
trust me, you're not alone

Malachi
I was going to work on some sorting algorithms in C# last time I watched them on Youtube. but never got to it. fibonacci is one of my favorites though and now Pisano Sequences are another one of my favorites
now seriously back to real work
any PHP Nerds in here?
