= PALP = == Description == 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. == License == * When released, GPL 2 was in force. * There is a link to a web page, which now points to GPL 3, but would have pointed to GPL 2 at the time the package was released. * Therefore one can deduce the authors were happy for this to be released under GPL 2 or a later version. == SPKG Maintainers == * William Stein == Upstream Contact == * Author: Harald Skarke (skarke@maths.ox.ac.uk) * Home page: http://hep.itp.tuwien.ac.at/~kreuzer/CY/CYpalp.html == Change log == === palp-2.1.p1 (Dima Pasechnik, 27 January 2013) === * #13960: as proposed by J.-P. Flori; set the stack size to 8MB for Cygwin. === palp-2.1.p0 (Volker Braun, 4th June 2012) === * #12088 Updated to the latest upstream version * Solaris sed does not understand character classes (:space:), dumb down even further * Removed the patched Polynf.c and MoriCone.c === palp-2.0.p2 (Volker Braun, 4th May 2012) === * #12088 change regex in spkg-install from \s to [[:space:]], only the latter works on OSX === palp-2.0.p1 (R. Andrew Ohana, 26th February 2012) === * #7071 Make spkg respect global CC and CFLAGS variables * made SAGE64 set the '-m64' flag the "proper" way === palp-2.0.p0 (Volker Braun, 19th November 2011) === * #12055 Update to new upstream version * Now building multiple versions for different ambient dimensions * Patched Polynf.c and MoriCone.c that do not use nested functions (private communication with Harald Skarke) === palp-1.1.p3 (David Kirkby, 24th May 2010) === * #9025 Add compiler option -m64 if the variable SAGE64 is set to "yes". The flag is added by 'sed'. === palp-1.1.p2 (Mitesh Patel, 12 Mar 2010) === * #8477: Work around apparent GNU make problem when building spkgs in parallel. * SPKG.txt cleanup. The description is based on the abstract of this paper: http://arxiv.org/abs/math/0204356 === palp-1.1.p1 (Tim Abbott, William Stein) === * Debian packaging. See 'hg log'. * Lost to history. | |||
