- class scipy.optimize.OptimizeResult#
Represents the optimization result.
OptimizeResultmay have additional attributes not listed here depending on the specific solver being used. Since this class is essentially a subclass of dict with attribute accessors, one can see which attributes are available using the
The solution of the optimization.
Whether or not the optimizer exited successfully.
Termination status of the optimizer. Its value depends on the underlying solver. Refer to message for details.
Description of the cause of the termination.
- fun, jac, hess: ndarray
Values of objective function, its Jacobian and its Hessian (if available). The Hessians may be approximations, see the documentation of the function in question.
Inverse of the objective function’s Hessian; may be an approximation. Not available for all solvers. The type of this attribute may be either np.ndarray or scipy.sparse.linalg.LinearOperator.
- nfev, njev, nhevint
Number of evaluations of the objective functions and of its Jacobian and Hessian.
Number of iterations performed by the optimizer.
The maximum constraint violation.
x.__getitem__(y) <==> x[y]
Create a new dictionary with keys from iterable and values set to value.
Return the value for key if key is in the dictionary, else default.
If key is not found, d is returned if given, otherwise KeyError is raised
Remove and return a (key, value) pair as a 2-tuple.
Insert key with a value of default if key is not in the dictionary.
If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
