CostFunctionResult(*, parameters, cost, cost_uncertainty=None)¶
Result from evaluating the user-defined cost function.
parameters (List[float]) – The parameters at which the cost function was evaluated.
cost (float) – The evaluated cost from the cost function.
cost_uncertainty (float) – Optional. The standard deviation in the value of the cost. For example, if the cost represents an average over several measurements, the uncertainty would be the standard error of those measurements.
