-solve nonlinear optimization problems.  Four types of problem are
-considered: unconstrained, equality constrained, inequality
-constrained and constrained.  Constraints may be applied as values of
-functions or sets of partial differential equations (PDEs).
-
-Solution algorithms such as the preconditioned nonlinear conjugate
-gradient method, sequential quadratic programming (SQP) and the
-primal-dual interior-point method are made available.  Interfaces are
-provided for applications written in C++ and Python.  Parallel
-computation is supported via MPI.")
