Hi all,

I just saw this announcement on NA Digest  (V. 16, #41) :

From: Joseph Young address@hidden
Date: October 25, 2016
Subject: Release of Optizelle 1.2.0

Optizelle [op-tuh-zel] is an open source software library designed to
solve general purpose nonlinear optimization problems.

Optizelle features

-- State of the art algorithms
- Unconstrained -- steepest descent, preconditioned nonlinear-CG,
  BFGS, Newton-CG, SR1, trust-region Newton, Barzilai-Borwein
  two-point approximation
- Equality constrained -- inexact composite-step SQP
- Inequality constrained -- primal-dual interior point method for cone
  constraints (linear, second-order cone, and semidefinite),
  log-barrier method for cone constraints
- Constrained -- any combination of the above

-- Open source
- Released under the 2-Clause BSD License
- Free and ready to use with both open and closed sourced codes

-- Multilanguage support
- Interfaces to C++, MATLAB/Octave, and Python

-- Robust computations and repeatability
- Can stop, archive, and restart the computation from any optimization

-- User-defined parallelism
- Fully compatible with OpenMP, MPI, or GPUs
