class squlearn.optimizers.optimizer_base.OptimizerBase

Base class for QNN optimizers.

minimize(fun: callable, x0: ndarray, grad: callable = None, bounds=None) → OptimizerResult

Function to minimize a given function.

Parameters:

• fun (callable) – Function to minimize.

• x0 (numpy.ndarray) – Initial guess.

• grad (callable) – Gradient of the function to minimize.

• bounds (sequence) – Bounds for the parameters.

Returns:

OptimizerResult format.

Return type:

Result of the optimization in class

set_callback(callback)

Set the callback function.
