Topic: Announcement of BOBYQA release by Michael J.D. Powell
(I've got to know about this one from Nils Wagner)
This Fortran software seeks the least value of a function of several variables
without requiring any derivatives of the objective function. It was developed
from my NEWUOA package for this calculation in the unconstrained case. The
main new feature of BOBYQA, however, is that it allows lower and upper bounds
on each variable. The name BOBYQA denotes Bound Optimization BY Quadratic
Please send an e-mail to me at mjdp-at-cam.ac.uk if you would like to receive a
free copy of the Fortran software. As far as I know BOBYQA is the most
powerful package available at present for minimizing functions of hundreds of
variables without derivatives subject to simple bound constraints. There are
no restrictions on its use. I would be delighted if it becomes valuable to
much research and many applications.

Currently I'm busy with a paid work and thus have a limited time for OpenOpt suite support on the forum.
