[SciPy-user] fmin_cobyla hangs
Tue Sep 4 02:22:40 CDT 2007
sometimes when running fmin_cobyla it never returns but keeps the cpu load high.
The last output (with iprint=2) is the following:
The initial value of RHO is 1.000000E+00 and PARMU is set to zero.
NFVALS = 1 F = 1.635286E+03 MAXCV = 5.335792E-02
X =-2.000000E-02 9.600000E-02 2.120000E-01 3.280000E-01 4.440000E-01
Increase in PARMU to 1.344559E+03
Increase in PARMU to 4.872087E+04
Does anybody know enough of the internals of fmin_cobyla to imagine what is
going on? In case it helps, I will try to build a sample script/data package.
