OpenOpt Suite release 0.33

New release 0.33 of OpenOpt Suite is out:

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), can work with non-Lipschitz and even some discontinuous functions
  
• 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 computations 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
