Rob,
I run the PyDSTool example "run_all_tests.py" on
python2.5.
Some tests failed, too. These failures seems to be
connected to 64 bit.
There seems to be another problem wrt fminbound.
fminbound(func, x1, x2, args=(),
xtol=1.0000000000000001e-05, maxfun=500, full_output=0,
disp=1)
Bounded minimization for scalar functions.
:Parameters:
func : callable f(x,*args)
Objective function to be minimized (must accept
and return scalars).
x1, x2 : float or array scalar
The optimization bounds.
args : tuple
Extra arguments passed to function.
xtol : float
The convergence tolerance.
maxfun : int
Maximum number of function evaluations allowed.
full_output : bool
If True, return optional outputs.
disp : int
If non-zero, print messages.
0 : no message printing.
1 : non-convergence notification messages
only.
2 : print a message on convergence too.
3 : print iteration results.
:Returns: (xopt, {fval, ierr, numfunc})
AFAIK the latest change wrt fminbound is
r5205 | stefan | 2008-11-29 13:41:23 +0100 (Sa, 29. Nov
2008) | 2 lines
In `fminbound`, raise an error if non-scalar bounds are
specified [patch by
Neil Muller]. Closes #544.
