Dear NLopt users,
NLopt 2.1.2 is now available from the NLopt web page (http://ab-initio.mit.edu/nlopt
), fixing a couple of minor bugs in the last release, and changing the
Python vector-valued constraint interface to use a more natural 2d
array for the gradient.
Regards,
Steven G. Johnson
NLopt 2.1.2 (8 July 2010)
* The Python mconstraint (vector-valued constraint) functions
now pass a 2-dimensional array for the gradient argument, rather
than a flattened 1d array.
* Improved handling of exceptions and forced stops for constrained
optimization, making sure that no constraints are evaluated after
the stop.
* Return an NLOPT_INVALID_ARGS error if more than n equality constraints
are added in an n-dimensional problem.
* Fix bug that could cause spurious NLOPT_INVALID_ARGS errors when
adding constraints under rare circumstances.
* Eliminate a few small memory leaks that could occur under error
conditions.
