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.

* Bump the LLVM revision used for GNUstep to 7, the minimum to support
the new ABI.
* GNUstep-back does not work with lld, so mark it to use Gold (BFD LD
doesn't seem able to link Objective-C things).
* Turn off some annoying debug logs in GNUstep back, which generate
several messages per second when you move the mouse. These should
never have been enabled in a release build anyway.
* Downgrade Cenon to 4.0.2. This was the last version to actually work
with GNUstep (the later ones use XCode >= 5 .xib files, which GNUstep
can't parse).
* Update gorm to git head. The current release doesn't work with the
new Objective-C ABI, but -head has the patches to fix it.
* Update PikoPixel and add it to the gnustep-app meta-package.
* Update the three core GNUstep packages to the latest release.
* Update gnumail and pantomime to the latest release and fix a linking
error with the new ABI.
* Update GNUstep FTP to the latest version.

These programs have been used in a number of other projects over
many years and they are highly portable and heavily tested.

pycma is a Python implementation of CMA-ES and a few related numerical
optimization tools.
The Covariance Matrix Adaptation Evolution Strategy (CMA-ES) is a stochastic
derivative-free numerical optimization algorithm for difficult (non-convex,
ill-conditioned, multi-modal, rugged, noisy) optimization problems in continuous
search spaces.
