longDescription = ''
|
|
A Package for Analyzing Lattice Polytopes (PALP) is a set of C
|
|
programs for calculations with lattice polytopes and applications to
|
|
toric geometry.
|
|
|
|
It contains routines for vertex and facet enumeration, computation of
|
|
incidences and symmetries, as well as completion of the set of lattice
|
|
points in the convex hull of a given set of points. In addition, there
|
|
are procedures specialised to reflexive polytopes such as the
|
|
enumeration of reflexive subpolytopes, and applications to toric
|
|
geometry and string theory, like the computation of Hodge data and
|
|
fibration structures for toric Calabi-Yau varieties. The package is
|
|
well tested and optimised in speed as it was used for time consuming
|
|
tasks such as the classification of reflexive polyhedra in 4
|
|
dimensions and the creation and manipulation of very large lists of
|
|
5-dimensional polyhedra.
|
|
|
|
While originally intended for low-dimensional applications, the
|
|
algorithms work in any dimension and our key routine for vertex and
|
|
facet enumeration compares well with existing packages.
