[SciPy-user] Simulated annealing in scipy

Hi all,
I tried to find the smallest eigenvalue of a generalized
eigenvalue problem
K x = \lambda M x
by minimizing the Rayleigh quotient
R = x^T K x / x^T M x
where K and M are symmetric positive definite.
I have used optimize.anneal for this purpose (annealing.py for details).
However, the simulated annealing algorithm doesn't terminate with the
global optimal solution.
But for what reason ?
Any pointer would be appreciated.
Regards,
Nils
