Triangulations Of Point Configurations and Oriented Matroids

http://www.rambau.wm.uni-bayreuth.de/TOPCOM/

TOPCOM is a package for computing Triangulations Of Point Configurations

and Oriented Matroids. It was very much inspired by the maple program

PUNTOS, which was written by Jesus de Loera. TOPCOM is entirely written

in C++, so there is a significant speed up compared to PUNTOS.
