GeneticSharp v2.2.0 - Sudoku sample

The GeneticSharp v2.2.0 is out.

The additions of this version are the new whole sample and extensions showing how to use GeneticSharp to solve a Sudoku.

The GeneticSharp.Extensions project receive those new features:

Multiple

MultipleChromosome

Compound chromosome to artificially increase genetics diversity by evolving a list of chromosomes instead of just one. Sub-genes are inlined into a single compound list of genes.

MultipleFitness

Fitness class that can evaluate a compound chromosome by summing over the evaluation of its sub-chromosomes.

Sudoku

ISudokuChromosome:

Represents each type of chromosome for solving a sudoku is simply required to output a list of candidate sudokus.

SudokuBoard

A class that represents a Sudoku, fully or partially completed. Holds a list of 81 int for cells, with 0 for empty cells. Can parse strings and files from most common formats and displays the sudoku in an easy to read format.

SudokuCellsChromosome

This simple chromosome simply represents each cell by a gene with a value between 1 and 9, accounting for the target mask if given.

SudokuFitness

Evaluates a sudoku chromosome for completion by counting duplicates in rows, columns, boxes, and differences from the target mask.

SudokuPermutationsChromosome

This more elaborated chromosome manipulates rows instead of cells, and each of its 9 gene holds an integer for the index of the row’s permutation amongst all that respect the target mask. Permutations are computed once when a new Sudoku is encountered, and stored in a static dictionary for further reference.

SudokuRandomPermutationsChromosome

This chromosome aims at increasing genetic diversity of SudokuPermutationsChromosome, which exhibits only 9 permutation genes. Here, instead, an arbitrary number of Sudokus are generated where for each row, a random gene is picked amongst an arbitrary number of corresponding permutation genes.

Thanks to

I would like to thanks to Jean-Sylvain Boige (@jsboige) for contributing with those great new samples and extensions and for use GeneticSharp in his Artificial Intelligence course in French engineering schools (course).

Take a look on the pull-request for fore details about those new features: New Sudoku extension and GTK# sample #43.

Let’s evolve!
