Définition

class OptimizeResult(_RichResult):

help(OptimizeResult)

Represents the optimization result.

Attributes
----------
x : ndarray
    The solution of the optimization.
success : bool
    Whether or not the optimizer exited successfully.
status : int
    Termination status of the optimizer. Its value depends on the
    underlying solver. Refer to `message` for details.
message : str
    Description of the cause of the termination.
fun : float
    Value of objective function at `x`.
jac, hess : ndarray
    Values of objective function's Jacobian and its Hessian at `x` (if
    available). The Hessian may be an approximation, see the documentation
    of the function in question.
hess_inv : object
    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, nhev : int
    Number of evaluations of the objective functions and of its
    Jacobian and Hessian.
nit : int
    Number of iterations performed by the optimizer.
maxcv : float
    The maximum constraint violation.

Notes
-----
Depending on the specific solver being used, `OptimizeResult` may
not have all attributes listed here, and they may have additional
attributes not listed here. Since this class is essentially a
subclass of dict with attribute accessors, one can see which
attributes are available using the `OptimizeResult.keys` method.
