    Hi all, I'm glad to inform you about new release 0.33 of our
    completely free (license: BSD) cross-platform software:

    OpenOpt:

    * cplex has been connected
    * New global solver interalg with guarantied precision, competitor
    to LGO, BARON, MATLAB's intsolver and Direct (also can work in inexact
    mode)
    * New solver amsg2p for unconstrained medium-scaled NLP and NSP

    FuncDesigner:

    * Essential speedup for automatic differentiation when vector-
    variables are involved, for both dense and sparse cases
    * Solving MINLP became available
    * Add uncertainty analysis
    * Add interval analysis
    * Now you can solve systems of equations with automatic
    determination is the system linear or nonlinear (subjected to given
    set of free or fixed variables)
    * FD Funcs min and max can work on lists of oofuns
    * Bugfix for sparse SLE (system of linear equations), that slowed
    down computation time and demanded more memory
    * New oofuns angle, cross
    * Using OpenOpt result(oovars) is available, also, start points
    with oovars() now can be assigned easier

    SpaceFuncs (2D, 3D, N-dimensional geometric package with abilities for
    parametrized calculations, solving systems of geometric equations and
    numerical optimization with automatic differentiation):

    * Some bugfixes

    DerApproximator:

    * Adjusted with some changes in FuncDesigner

    Regards, Dmitrey.
