OptimizerState

class 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: float | ndarray

Current optimization parameters.

fun: Callable[[float | ndarray], float] | None

Function being optimized.

jac: Callable[[float | ndarray], float | ndarray] | None

Jacobian of the function being optimized.

nfev: int | None

Number of function evaluations so far in the optimization.

njev: int | None

Number of jacobian evaluations so far in the optimization.

nit: int | None

Number of optimization steps performed so far in the optimization.
