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

entries in Twitter and Facebook, see http://openopt.org for details.
