abstract

PDS is a collection of Fortran subroutines for solving unconstrained
nonlinear optimization problems using direct search methods.
The software is written so that execution on sequential machines is
straightforward while execution on Intel distributed memory machines
can be accomplished simply by including a few well-defined routines
containing calls to Intel-specific Fortran libraries.
