[Numpy-discussion] Ann: OpenOpt and FuncDesigner 0.37

[Dmitrey]

Hi all,
I'm glad to inform you about new release 0.37 (2011-Dec-15) of our free
software:

>

OpenOpt (numerical optimization):

>

IPOPT initialization time gap (time till first iteration) for
FuncDesigner models has been decreased
Some improvements and bugfixes for interalg, especially for "search all
SNLE solutions" mode (Systems of Non Linear Equations)
Eigenvalue problems (EIG) (in both OpenOpt and FuncDesigner)
Equality constraints for GLP (global) solver de
Some changes for goldenSection ftol stop criterion
GUI func "manage" - now button "Enough" works in Python3, but "Run/Pause"
not yet (probably something with threading and it will be fixed in Python
instead)

>

FuncDesigner:
Major sparse Automatic differentiation improvements for badly-vectorized
or unvectorized problems with lots of constraints (except of box bounds);
some problems now work many times or orders faster (of course not faster
than vectorized problems with insufficient number of variable arrays). It
is recommended to retest your large-scale problems with useSparse =
'auto' | True| False

>

Two new methods for splines to check their quality: plot and residual
Solving ODE dy/dt = f(t) with specifiable accuracy by interalg
Speedup for solving 1-dimensional IP by  interalg

>

SpaceFuncs and DerApproximator:

>

Some code cleanup

>
