Review: nlopt 2.11.0-1

Package Information

Descriptionnonlinear optimization library

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

* Callable from C, C++, Fortran, GNU Octave, Python, GNU Guile, GNU R. * A common interface for many different algorithms * Support for large-scale optimization. * 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.

This package provides the shared libraries required to run programs compiled with NLopt. To compile your own programs you also need to install libnlopt-dev.

Thanks

INCOMPATIBLE WITH DFSG (1):
  BSD-4-Clause-UC                     [BSD 4-Clause UC (original UC Berkeley advertising clause)]

    This license contains an advertising clause requiring that all advertising
    materials mentioning features or use of the software display a specific
    acknowledgment of the original author or institution.
    
    The advertising clause is DFSG-incompatible for two reasons:
    
    1. Accumulation problem: When a program incorporates multiple components each
    carrying an advertising clause with a different required acknowledgment, every
    advertising material for the combined work must carry all of them. With even a
    handful of such components this becomes unmanageable, and Debian packages
    routinely include dozens of third-party libraries. This places an unreasonable
    restriction on redistribution, violating DFSG §1.
    
    2. GPL incompatibility: The advertising clause is an additional restriction
    beyond what GPL §7 permits. Combining advertising-clause code with GPL-licensed
    code in the same binary or Debian package is therefore a licence violation. The
    FSF has explicitly documented the 4-clause BSD and MIT advertising variants as
    GPL-incompatible for this reason.
    
    The FreeBSD project removed the advertising clause from its own code in 1999;
    the OpenBSD and NetBSD projects followed suit. New upstream code using this
    licence should be encouraged to relicense without the advertising clause.

Result: ATTENTION REQUIRED
  - 1 DFSG-incompatible license(s) found
