CostHistory

class qctrl.dynamic.types.stochastic_optimization.CostHistory(*, iteration_values=None, historical_best=None)

The cost history of a stochastic optimization. Its contents depend on the cost_history_scope selected.

Variables:

• iteration_values (List[float], optional) – The list of values of the cost function obtained at each iteration.

• historical_best (List[float], optional) – The list of best historical values of the cost function reached up to each iteration.
