class parpe::HierarchicalOptimizationReporter : public parpe::OptimizationReporter

The HierarchicalOptimizationReporter class saves optimization parameters of the inner optimization problem on each function evaluation which would be hidden from the (outer) optimizer otherwise.

Public Functions

HierarchicalOptimizationReporter(HierarchicalOptimizationWrapper *gradFun, std::unique_ptr<OptimizationResultWriter> rw, std::unique_ptr<Logger> logger)
virtual FunctionEvaluationStatus evaluate(gsl::span<const double> parameters, double &fval, gsl::span<double> gradient, Logger *logger = nullptr, double *cpuTime = nullptr) const override
virtual bool iterationFinished(gsl::span<const double> parameters, double objectiveFunctionValue, gsl::span<const double> objectiveFunctionGradient) const override

Is called after each iteration except for the last one.

Parameters

  • parameters –

  • objectiveFunctionValue –

  • objectiveFunctionGradient –

Returns

Quit optimization?

virtual bool afterCostFunctionCall(gsl::span<const double> parameters, double objectiveFunctionValue, gsl::span<double const> objectiveFunctionGradient) const override
virtual void finished(double optimalCost, gsl::span<const double> parameters, int exitStatus) const override

Is called after optimization finished.

virtual std::vector<double> const &getFinalParameters() const override
