I had tested an early diff from pirofti that fixed BUILD_DEPENDS but
also bumped REVISION. In the meantime sthen had just fixed them without
the unnecessary REVISION bump. Bumping REVISION will get them building
on sparc64 again.
4ti2 is a software package for algebraic, geometric and combinatorial
problems on linear spaces. It computes Graver basis, Groebner basis,
in case of a linear , matrix or more general lattice program and a lot
more programs in linear spaces.

The C-library cddlib can be used for the reverse operation (i.e. convex hull
computation). This means that one can move back and forth between an inequality
representation and a generator (i.e. vertex and ray) representation of a
polyhedron with cddlib. Also, cddlib can solve a linear programming problem,
i.e. a problem of maximizing and minimizing a linear function over P.

for this name, plus convergence with other packaging systems that use this
name.
While here, update bc-gh to version 3.1.1. Also improve 64-bit check in the
Makefile.

This is an implementation of the POSIX bc calculator that implements GNU
bc extensions as well as the period (.) extension from the BSD flavor of
bc.
This bc also includes an implementation of dc in the same binary,
accessible via a symbolic link, which implements all *BSD and GNU
extensions, though the ! command is omitted for security concerns.

Works; improvements in-tree to come.
RStudio is an integrated development environment (IDE) for R.
It includes a console, syntax-highlighting editor that supports direct
code execution, as well as tools for plotting, history, debugging and
workspace management.
The OSQP (Operator Splitting Quadratic Program) solver is a numerical
optimization package for solving convex quadratic programs in the form
minimize (1/2)x'Px+q'x
subject to l <= Ax <= u
where x is the optimization variable and P is a positive semidefinite matrix.

SCS (splitting conic solver) is a numerical optimization package
for solving large-scale convex cone problems, based on our paper
Conic Optimization via Operator Splitting and Homogeneous Self-Dual
Embedding.
It is written in C and can be used in other C, C++, Python, Matlab,
R, Julia, and Ruby, programs via the linked interfaces.
It can also be called as a solver from convex optimization toolboxes
CVX (3.0 or later), CVXPY, Convex.jl, and Yalmip.
CVXPY is a Python-embedded modeling language for convex optimization
problems. It allows you to express your problem in a natural way
that follows the math, rather than in the restrictive standard form
required by solvers.
CVXOPT is a free software package for convex optimization based on
the Python programming language. It can be used with the interactive
Python interpreter, on the command line by executing Python scripts,
or integrated in other software via Python extension modules. Its
main purpose is to make the development of software for convex
optimization applications straightforward by building on Python's
extensive standard library and on the strengths of Python as a
high-level programming language.
ECOS is a numerical software for solving convex second-order cone
programs (SOCPs) of type
min c'x
s.t. Ax = b
Gx <=_K h
where the last inequality is generalized, i.e. h - Gx belongs to the
cone K.
