https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231186 --- Comment #5 from commit-hook@freebsd.org --- A commit references this bug: Author: tobik Date: Fri Feb 8 09:27:35 UTC 2019 New revision: 492416 URL: https://svnweb.freebsd.org/changeset/ports/492416 Log: New ports: math/gfan, math/gfanlib Gfan is a software package for computing Groebner fans and tropical varieties. These are polyhedral fans associated to polynomial ideals. The maximal cones of a Groebner fan are in bijection with the marked reduced Groebner bases of its defining ideal. The software computes all marked reduced Groebner bases of an ideal. Their union is a universal Greobner basis. The tropical variety of a polynomial ideal is a certain subcomplex of the Groebner fan. Gfan contains algorithms for computing this complex for general ideals and specialized algorithms for tropical curves, tropical hypersurfaces and tropical varieties of prime ideals. In addition to the above core functions the package contains many tools which are useful in the study of Groebner bases, initial ideals and tropical geometry.
