EuropeanCallDelta
class EuropeanCallDelta(uncertainty_model, strike_price, i_state=None, i_objective=None)
The European Call Option Delta.
Evaluates the variance for a European call option given an uncertainty model. The payoff function is f(S, K) = max(0, S - K) for a spot price S and strike price K.
Constructor.
Parameters
- uncertainty_model (
UnivariateDistribution) – uncertainty model for spot price - strike_price (
float) – strike price of the European option - i_state (
Union[List[int],ndarray,None]) – indices of qubits representing the uncertainty - i_objective (
Optional[int]) – index of qubit for objective function
Attributes
num_target_qubits
Returns the number of target qubits
