Kaiketsu

I recently had the pleasure of testing out Kaiketsu, a simple yet efficient sudoku solver. This software truly lives up to its name, which means "heroic" in Japanese, as it quickly and accurately solves even the most complex of sudoku puzzles.

The installation process is a breeze. Simply navigate to the directory containing the source code and run `./configure` to configure the package for your specific system. If you are using an older version of System V, you may need to type `sh ./configure` instead to prevent `csh` from trying to execute `configure` itself. The `configure` process may take a few moments, during which it will print some informative messages about the features it is testing for.

After configuring, running `make` compiles the package while `make install` takes care of installing the programs, data files, and documentation. Additionally, you can clean out the program binaries and object files from the source code directory with `make clean`.

One of the great new features of Kaiketsu's latest release is the improved speed, thanks to developer Cedric LeGloannec. It is now possible to find all the solutions of a sudoku scheme and save them into a file. Overall, I would highly recommend this software for anyone who enjoys sudoku and wants a reliable and user-friendly solver.
