[SciPy-User] criteria's to get the exit mode '0

[jagan prabhu]

Hi,

I am using the scipy optimization routine 'fmin_slsqp' and  'fmin_l_bfgs_b' in both the case exit mode '0' represents optimization terminated successfully / convergence is achieved.

What are the criteria's to get the exit mode '0' ?

Because if i change my initial parameters by very small increment or decrement, i am getting huge difference in my optimized functional value & optimized parameter values. 

so i like to know,
How do the optimization routine determines this the optimized parameters and optimized functional value?

Thank you in advance.

Regards,
Jagan
