Dear NLopt users, NLopt version 2.3 is now available from the NLopt web page (ab-initio.mit.edu/nlopt). This is an incremental release to make available some bugfixes and minor features that have accumulated over the past year.
Regards, Steven G. Johnson NLopt 2.3 (20 July 2012) * In Matlab/Octave interface, make returning NaN from the objective equivalent to nlopt_force_stop; thanks to Norman Violet for the suggestion. * Added CCSA-quadratic (NLOPT_LD_CCSAQ), similar to MMA. * Added interface for supplying a preconditioner (approximate Hessian); currently only supported in CCSAQ. * When adding mconstraints, allow tol==NULL as synonym for zero tolerances. * Added missing NLOPT_LD_SLSQP constant in Matlab/Octave. * Lower tolerance for dual optimization in MMA/CCSAQ; thanks to Christophe Leruste for the problem report * Fixed bug in timer, thanks to William Vaughn for the patch. * Bug fix to convergence test in sbplx; thanks to Douglas Bates. _______________________________________________ NLopt-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/nlopt-discuss
