Methods
combine
VQEResult.combine(result)
Any property from the argument that exists in the receiver is updated. :type result: AlgorithmResult :param result: Argument result with properties to be set.
Raises
TypeError – Argument is None
Return type
None
Attributes
aux_operators_evaluated
The aux operator expectation values.
These values are in fact tuples formatted as (mean, (variance, shots)).
cost_function_evals
The number of cost optimizer evaluations.
Return type
int | None
eigenvalue
The computed minimum eigenvalue.
Return type
complex | None
