polymake is a software package designed for the study of the combinato rics and the geometry of convex polytopes and polyhedra. It offers access to a wide variety of algorithms and tools within a common framework. As a key design feature it allows to incorporate the functionality of a great variety of other software packages in a modular way. polymake is… (More)
We describe an XML file format for storing data from computations in algebra and geometry. We also present a formal specification based on a RELAX-NG schema.
This note wants to explain how to obtain meaningful pictures of (possibly high-dimensional) convex polytopes, triangulated manifolds, and other objects from the realm of geometric combinatorics such as tight spans of finite metric spaces and tropical polytopes. In all our cases we arrive at specific, geometrically motivated, graph drawing problems. The… (More)
