GoemansWilliamsonOptimizationResult

class GoemansWilliamsonOptimizationResult(x, fval, variables, status, samples, sdp_solution=None)

Bases: OptimizationResult

Contains results of the Goemans-Williamson algorithm. The properties x and fval contain values of just one solution. Explore samples for all possible solutions.

Parámetros:

• x (List[float] | ndarray | None) – the optimal value found in the optimization.

• fval (float) – the optimal function value.

• variables (List[Variable]) – the list of variables of the optimization problem.

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

• samples (List[SolutionSample] | None) – the solution samples.

• sdp_solution (ndarray | None) – an SDP solution of the problem.
