tomka@gentoo.org Thomas Kahle sci-mathematics@gentoo.org Gentoo Mathematics Project Enable sci-libs/cddlib interface for convex hull computations (Should be kept enabled). Enable sci-libs/lrslib interface for convex hull computations. Enable dev-libs/ppl interface for convex hull computations. Enable sci-libs/bliss interface for graph and face lattice isomorphism computations. Build extension for dealing with permutation groups and symmetric objects. Build the bundled extension for lattice related computations. Enable the interface to sci-mathematics/singular for ideal related computations. Build the polymake library to build applications using the C++ interface. Polymake started out as a tool for the algorithmic treatment of convex polyhedra. By now it also deals with finite simplicial complexes, tight spans of finite metric spaces, and other objects.
