class RecursiveMinimumEigenOptimizationResult(x, fval, variables, status, replacements, history)

Recursive Eigen Optimizer Result.

Constructs an instance of the result class.

매개변수

• x (Union[List[float], ndarray]) – 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.

• replacements (Dict[str, Tuple[str, int]]) – a dictionary of substituted variables. Key is a variable being substituted, value is a tuple of substituting variable and a weight, either 1 or -1.

• history (Tuple[List[MinimumEigenOptimizationResult], OptimizationResult]) – a tuple containing intermediate results. The first element is a list of MinimumEigenOptimizerResult obtained by invoking MinimumEigenOptimizer iteratively, the second element is an instance of OptimizationResult obtained at the last step via min_num_vars_optimizer.
