alienDeveloperon Show HN: Solving Sudoku using PHP.

Well the constraint propagation is quite good. My logic adds one more constraint.

If any of the possible values of a cell is not possible in any of the other conflicting cell than its safe to assume that, that value is the value of this cell.

hope its not confused. check the line 313 to 386 of my code.

because brute-force executes very quickly for easy sudoku's but as it gets harder and lesser values are provided it takes too much time.

this is not a brute force trick.. it calculate all possibilities and eliminate others using constraint theories.

alienDeveloperon Poll: Which 3 languages would you learn

Well i already know php to some extend, and the basics of C/CPP, Java, Action Script and all..

But i really like to get my hands dirty on C/CPP(im working on a MySQL storage engine as a hobby) and i like to learn python( i like maya[Animation], not only that python is a very strong language) too .. Those are the 2 currently in my list..

And if u want me to chose one more.. i say Java, because it will give me a very strong background on some very kewl concepts which i can use in other languages.. :)

And about my natural languages..

I definitely like to learn Sanskrit because their is a lot of knowledge hidden in Sanskrit books which u can never find else where, then i like to learn Chinese because i like the way its pronounced. and finaly spanish because.. well their is no because for that.. i just like to learn thats all.. :)

actually its harder than i thought it will be to reason why you learn a natural language other than if you are going to visit the related country or you are dating someone from that country ;) ..
