[Pla09] contains the
asynchronous parallel pattern search (APPS) algorithm
[GK06]. It can handle unconstrained
problems as well as those with bound constraints, linear constraints,
and general nonlinear constraints.
HOPSPACK is available to the
public under the GNU LGPL and the source code is included with Dakota.
