My Sudoku Solver - Next Version.

I am happy to share with you, my next Sudoku Solver - Beta2


In one of my previous posting, I told about the first Sudoku solver I had developed. Well, I could improve something and I think this is more helpful.

Unlike the original (beta), this new one (beta-2) do the solving in real logic. And is Interactive. I mean, the user can choose to explain the logic of each step. I think this will help the beginners very much. Also for others, it can come as handy if they are stuck at any position.

Its was fun making this. I think its worth the sleep I lost over this, if atleast one person found it useful... Hope it does..

Its already early morning 4 'o clock.. I need to go to bed atleast now..

I created a Sudoku Solver..

I have created a Solver for Sudoku Puzzles.. It was exciting..


As you may have seen in one of my older post, I had started playing sudoku.. But then, in between I started thinking of making a solver in excel.. But that was all what I had got, just an interest.. Then i got a rough logic.. This weekend, I was thinking what to do! So I thought of giving it a try.. Same old destination.. Thanks to all those wonderful guys in Google Groups, I got the syntax for making functions.. The C/C++ fundamentals came handy as well.. One by one the pieces of the puzzle came together and less than 10 hours on the job, I got the first result.. That fealing is wonderfull..

So I have uploaded the file in the following location.. Check that out!
Its just the first cut..

This was interesting..

Its the Sudoku.

Having a got a good link the other day, I started trying to solve.

If you have not heard, which is unlikely, its a puzzle. Its a game that needs bit of logic and patience. Normal game is a 9x9 matrix which is sub-divided into nine 3x3 matrix. The objective is to fill the numbers 1-9 in each cell in such a way that each 3x3 matrix and each row / column will not have any repetetion. Generally the puzzle will be given insuch a way that there is a solution and only one solution which u can reach by logic and not by guessing.



I had already heard abt the game and knew the rules, but just a beginner. Created a login and started trying. I got a couple solved and got excited. And there is this puzzle which I was sure that it was having more than one solution. I took snapshot at each stage to proove to the providers that I have found this out. After a lot of painstaking work, I eneded up finding that I was wrong. I lost the sleep for nothing. :)) But it was fun..

This was the site where I was..

Interstingly this game has a long history but got popular in Europe recently thanks to the work of Wayne Gould (born 1945 in New Zealand) is a retired Hong Kong judge. He saw this game accidently in Japan and got addicted to it. He worked on it and developed a software for creating the puzzles. He ditributed it for free to the UK Newspapers and it caught up like that..
