For instructions on how to use the bfh_python program, see the documentation by Robert Lipshitz.

You can also install it as a self-contained Python package using pip by following these instructions.

The program bfh_python is based on a previous program (written in Sage) by Robert Lipshitz, Peter Ozsvath and Dylan Thurston, which is available on the former's webpage.

Implements various algorithms described in the following papers of R. Lipshitz, P. Ozsvath, and D. Thurston
