OptimizerState
class qiskit.algorithms.optimizers.OptimizerState(x, fun, jac, nfev, njev, nit)
Bases: object
Base class representing the state of the optimizer.
This class stores the current state of the optimizer, given by the current point and (optionally) information like the function value, the gradient or the number of function evaluations. This dataclass can also store any other individual variables that change during the optimization.
Attributes
x
Typ: POINT
Current optimization parameters.
fun
Typ: Callable[[POINT], float] | None
Function being optimized.
jac
Typ: Callable[[POINT], POINT] | None
Jacobian of the function being optimized.
nfev
Typ: int | None
Number of function evaluations so far in the optimization.
njev
Typ: int | None
Number of jacobian evaluations so far in the opimization.
nit
Typ: int | None
Number of optimization steps performed so far in the optimization.
