polybori
polynomials over Boolean Rings, custom ipython shell
The core of PolyBoRi is a C++ library, which provides high-level data
types for Boolean polynomials and monomials, exponent vectors, as
well as for the underlying polynomial rings and subsets of the
powerset of the Boolean variables. As a unique approach, binary
decision diagrams are used as internal storage type for polynomial
structures. On top of this C++-library a Python interface
is provided. This allows parsing of complex polynomial systems, as well
as sophisticated and extendable strategies for Groebner base
computation. PolyBoRi features a powerful reference implementation
for Groebner basis computation.
