./math/nlopt, Nonlinear optimization library

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.10.0, Package name: nlopt-2.10.0, Maintainer: pkgsrc-users

NLopt is a free/open-source library for nonlinear optimization,
providing a common interface for a number of different free optimization
outines available online as well as original implementations of various
other algorithms.

Its features include:
- Callable from C, C++, Fortran, Matlab or GNU Octave, Python,
GNU Guile, Julia, GNU R, Lua, and OCaml.
- A common interface for many different algorithms -- try a different
algorithm just by changing one parameter.
- Support for large-scale optimization (some algorithms scalable to
millions of parameters and thousands of constraints).
- Both global and local optimization algorithms.
- Algorithms using function values only (derivative-free) and also
algorithms exploiting user-supplied gradients.
- Algorithms for unconstrained optimization, bound-constrained
optimization, and general nonlinear inequality/equality constraints.

Log message:
nlopt: updated to 2.10.0

NLopt 2.10

* New Java bindings
* Allow disabling exceptions with `set_exceptions_enabled`
* Configurable `tolg` tolerance parameter for Luksan gradient stopping condition
* Restored `LD_LBFGS_NOCEDAL` enum value (dropped in 2.9) to ease backwards \ 
compatibility for wrappers in other languages (though this algorithm is \ 
currently unimplemented)

Log message:
nlopt: updated to 2.9.1

NLopt 2.9.1

* Fixed PRAXIS box constraints

NLopt 2.9

* New `NLOPT_LUKSAN` cmake option to build without Luksan LGPL code

* Dropped unused LD_LBFGS_NOCEDAL enum value.

* Python 3.13 support

* Fixed COBYLA not returning the optimum

* Fixed SLSQP returning infeasible optimum

* Fixed STOGO not registering new optimum

* Various minor bugfixes

NLopt 2.8

* Support C++ functors for objective functions

* CCSA/MMA an now use the `initial_step` parameter to bound their initial stepsize,
  and also expose a new internal parameter `rho_init`

* Install `pkg-config` file on Windows

* Allow having more equality constraints than there are variables

* Bugfixes to `nlopt_algorithm_name`
