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
>
