Java Oriented Matroids API

Manipulates oriented matroids: switching between cryptomorphisms: circuits, co-circuits, vectors, co-vectors, maximum vectors, topes, chirotopes, and realizations, and dual realizations.

Packages 
Package Description
net.sf.oriented.omi
This package is the public interface, with OM as the key interface defining oriented matroids.
net.sf.oriented.pseudoline
This package is for representing rank 3 oriented matroids as pseudoline drawings, particularly in the Euclidean plane.
net.sf.oriented.util.combinatorics
A few additional combinatoric related classes and functions needed for this library.
net.sf.oriented.util.matrix
Minimal extension over the Apache Commons Math Library required for this library.
oriented
Command line tools.

Manipulates oriented matroids: switching between cryptomorphisms: circuits, co-circuits, vectors, co-vectors, maximum vectors, topes, chirotopes, and realizations, and dual realizations. The main reference used for developing and helpful in use of this library is Oriented Matroids, 1999, by Björner et al.

The primary focus of the work, is on developing a new algorithm for realizability in rank 3. The libary is a side effect.
