arnoux_yoccoz_0.1_cpp

A program for searching for pseudo-anosov homeomorphisms. This is the first version, written in C++. It only works for the projective plane, and even there only in a very special case.

arnoux_yoccoz_0.2_cpp_qt

The second version of the pseudo-anosov searching program. Added graphical interface and generalized the algorithm compared to version 0.1. It builds and runs but it is unfinished and abandoned.

arnoux_yoccoz_0.3_sage_old

The third version of the Arnoux-Yoccoz project. The algorithm is highly generalized to work on any finite type surface, but it is also simpler, more elegant, and faster than previously.
