Here is an implementation of the Schulze STV method:

http://m-schulze.webhop.net/schulze3.zip

The file "calcul01.pdf" explains how I implemented
proportional completion.

The file "calcul02.pdf" explains how I calculate
the strengths of the vote managements.

"prog01.c" and "prog01.exe" are implementations of
the Schulze STV method in Microsoft Visual C++ 5.0.

The file "schulze3.zip" also contains many instances.

Here, I applied the Schulze STV method to the
2007 elections at SPI:
