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


    * 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
    * New solver amsg2p for unconstrained medium-scaled NLP and NSP


    * 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


    * Adjusted with some changes in FuncDesigner
