SlsqpOptimizationResult#

class SlsqpOptimizationResult(x, fval, variables, status, fx=None, its=None, imode=None, smode=None)[fuente]#

Bases: OptimizationResult

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

Constructs a result object with properties specific to SLSQP.

Parámetros:

  • x (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 (ndarray | None) – The value of the objective function being optimized, may be different from fval

  • its (int | None) – The number of iterations.

  • imode (int | None) – The exit mode from the optimizer (see the documentation of scipy.optimize.fmin_slsqp).

  • smode (str | None) – Message describing the exit mode from the optimizer.

  • status (OptimizationResultStatus) – the termination status of the optimization algorithm.
