class RecursiveMinimumEigenOptimizationResult(x, fval, variables, status, replacements, history)
Recursive Eigen Optimizer Result.
Constructs an instance of the result class.
Parameters
- 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 ofMinimumEigenOptimizerResultobtained by invokingMinimumEigenOptimizeriteratively, the second element is an instance ofOptimizationResultobtained at the last step via min_num_vars_optimizer.
