# Binary sudoku online game

Generating the grids was fast but checking was slow. Given a grid, you first apply the simple rules above. I very quickly realized that I could reduce the problem space significantly simply by applying the binary sudoku online game deterministic rules that you use when solving the puzzles by hand.

That worked on 8x8 grids, but beyond that things became too slow. I could binary sudoku online game the most trivial puzzles quickly, but the iterative approach I had implemented was far too inefficient to solve the more complex ones. And it only took 3 years ;- The puzzles are a little like sudoku. However, I now had a test case from binarypuzzle.

For now though, my Binary Puzzle solver code is on GitHub and I welcome feedback, criticism or contributions. You get a grid which contains a number of ones and zeros and you fill it binary sudoku online game with more ones and zeros, until each row and column of the grid. I thought so and started to write some Haskell code that would solve the puzzles. Binary sudoku online game got me to being able to solve my test puzzle from the book with my original Cartesian product approach.

That worked on 8x8 grids, but beyond that things became too slow. Otherwise take the shortest element with more than one entry and create matrices for each entry, filter for matrices that are filled with single entry elements and generate valid grids and return the first of those. A couple of days before New Year binary sudoku online game be precise.

Given a grid, you first apply the simple rules above. Then you generate a "matrix", which is a list in binary sudoku online game each element is the rows that could possibly be answers for that grid. And it only took 3 years ;- The puzzles are a little like sudoku.
