Risodukore wasn't designed for matrices with a fixed number of fields: it reads
the size of the square by the first row of the file.
This puzzle game is very popular in the 9x9 version, but the program has been tested on 4x4, 16x16 and 25x25
as well.
For example, using a computer with first generation of pentium centrino processor, it solved in 39 seconds
a jumbo sudoku (25x25), published in the newspaper Il Secolo XIX on the 15th August 2005, with a
full scanning of the space of solutions in 8 minutes.
To use the program you should copy it in a folder containing the input file: the easiest way is to name it in.txt. You can also use a file with a different name and execute the program using the string: RisodukoreF -i filename.extension
The input file must be as follows:
1 0 0 4 0 2 3 0 0 4 1 0 3 0 0 2 |
1 | 4 | ||
2 | 3 | ||
4 | 1 | ||
3 | 2 |
The program creates two html output files: solution and step by step progression.
