PolyBoRi: 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 we provide a Python interface. This allows parsing of complex polynomial systems, as well as sophisticated and extendable strategies for Gröbner base computation. PolyBoRi features a powerful reference implementation for Gröbner basis computation. PolyBoRi is a joint project of the following institutions * Mathematisches Forschungsinstitut Oberwolfach (MFO), Oberwolfach, Germany, * University of Kaiserslautern, Department of Mathematics, Algebra, Geometry and Computer Algebra Group, Kaiserslautern, Germany, and * Fraunhofer Institute for Industrial Mathematics (ITWM), Department of System Analysis, Prognosis and Control, Kaiserslautern, Germany. Release Name: 0.8.0 * improved standard-conformity, multiprocessing safety, and usability * renamed subdirectory polybori to libpolybori * new directory structure in libpolybori/include and groebner/include * libgroebner renamed libpolybori_groebner * using only part of CUDD (linked into libpolybori) * officially introducing VariableBlock * removed all global settings and BooleEnv itself * added factories and RingContext to replace active/global ring * improved multiprocessing and pickling * added inSingleBlock/in_single_block to polynomials * for avoiding name clashes Cudd's headers install into include/polybori/cudd * Introducing WeakRingPtr for managing weak references to rings on C++ level * python level: deprecated Ring changing routines change_ordering, set_variable_names, append_block, use extended arguments of Ring.__init__() and Ring.clone(). * ipython 0.11 compatibility established (hint from the Fedora team. Thanks!) * libM4RI compatibility re-established (hint from Martin Albrecht. Thanks!) * distributed targed uses world-readable permissions * cluster.py: very experimental Python module for finding an overdetermined subset of equations
