Description

DOT library [Vanderplaats Research and Development, Inc.95] implementation of the modified method of feasible directions for constrained optimizaiton.

See Package: DOT for information common to all DOT methods.

DOT requires a separate software license and therefore may not be available in all versions of Dakota. CONMIN or OPT++ methods may be suitable alternatives.

Expected HDF5 Output

If Dakota was built with HDF5 support and run with the hdf5 keyword, this method writes the following results to HDF5:
