qiskit.optimization.algorithms.SlsqpOptimizationResult¶

class SlsqpOptimizationResult(x, fval, variables, status, fx=None, its=None, imode=None, smode=None)[ソース]¶

SLSQP optimization result, defines additional properties that may be returned by the optimizer.

Constructs a result object with properties specific to SLSQP.

パラメータ

x (Union[List[float], ndarray]) – The solution of the problem
fval (float) – The value of the objective function of the solution
variables (List[Variable]) – A list of variables defined in the problem
fx (Optional[ndarray]) – The value of the objective function being optimized, may be different from fval
its (Optional[int]) – The number of iterations.
imode (Optional[int]) – The exit mode from the optimizer (see the documentation of scipy.optimize.fmin_slsqp).
smode (Optional[str]) – Message describing the exit mode from the optimizer.
status (OptimizationResultStatus) – the termination status of the optimization algorithm.
