Scipy Minimize

class pbparam.ScipyMinimize(method=None, extra_options=None, optimiser_options=None)

Scipy Minimize class.

This class is a wrapper around the scipy.optimize.minimize function and uses various minimization methods. The ‘Nelder-Mead’ method is faster to converge and robust.Please refer to (https://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.minimize.html) for more details.

Parameters:

• method (str or callable) –

  Type of solver. Should be one of

  ‘Nelder-Mead’

  ‘Powell’

  ‘CG’

  ‘BFGS’

  ‘Newton-CG’

  ‘L-BFGS-B’

  ‘TNC’

  ‘COBYLA’

  ‘SLSQP’

  ‘trust-constr’

  ‘dogleg’

  ‘trust-ncg’

  ‘trust-exact’

  ‘trust-krylov’

  custom - a callable object

• extra_options (dict, optional) – Dict of arguments that will be used in optimiser.
