- scipy.optimize.minimize(fun, x0, args=(), method=None, jac=None, hess=None, hessp=None, bounds=None, constraints=(), tol=None, callback=None, options=None)
Minimization of scalar function of one or more variables using the conjugate gradient algorithm.
For documentation for the rest of the parameters, see
Set to True to print convergence messages.
Maximum number of iterations to perform.
Gradient norm must be less than gtol before successful termination.
Order of norm (Inf is max, -Inf is min).
- epsfloat or ndarray
If jac is None the absolute step size used for numerical approximation of the jacobian via forward differences.
- return_allbool, optional
Set to True to return a list of the best solution at each of the iterations.
- finite_diff_rel_stepNone or array_like, optional
If jac in [‘2-point’, ‘3-point’, ‘cs’] the relative step size to use for numerical approximation of the jacobian. The absolute step size is computed as
h = rel_step * sign(x) * max(1, abs(x)), possibly adjusted to fit into the bounds. For
method='3-point'the sign of h is ignored. If None (default) then step is selected automatically.
