Suku 
The sudoku library - a war on 9x9 grids.
by Lee-Jon
Goal
My aim in creating Suku is creating a ruby library for manipulating, generating and solving Sudoku games.
At present version 0.1, this is a learning exercise, so code can be badly factored and is often without tests - and some code is more exploratory and unoptimised. The aim is to get basic board manipulation done before moving on to brute-force, backtracing, and then the basic logical solvers.
Once this is completed 0.2+ will create a game loop, and solving loop to incrementally solve any Sudoku puzzle.
To do will be Sudoku puzzle generation, and the more advanced logic solvers.
Features
Currently there are two classes:
- Board - which encapsulates a 9x9 grid
- Logical - which encapsulates all the logic methods to solve a board
Also included is solve_by_brute_force.rb, which is a brute force algorithm.
Help out!
I'm not a programmer by profession, only for fun. So any advice on how to refactor, structure or code is welcomed!
