Detailed Description

Wrapper class for the PSUADE library.

The PSUADEDesignCompExp class provides a wrapper for PSUADE, a C++ design of experiments library from Lawrence Livermore National Laboratory. Currently this class only includes the PSUADE Morris One-at-a-time (MOAT) method to uniformly sample the parameter space spanned by the active bounds of the current Model. It returns all generated samples and their corresponding responses as well as the best sample found.

Constructor & Destructor Documentation

PSUADEDesignCompExp()

PSUADEDesignCompExp	(	ProblemDescDB &	problem_db,
		Model &	model
	)

primary constructor for building a standard DACE iterator

This constructor is called for a standard iterator built with data from probDescDB.

Member Function Documentation

pre_run()

void pre_run ( )

protectedvirtual

pre-run portion of run (optional); re-implemented by Iterators which can generate all Variables (parameter sets) a priori

pre-run phase, which a derived iterator may optionally reimplement; when not present, pre-run is likely integrated into the derived run function. This is a virtual function; when re-implementing, a derived class must call its nearest parent's pre_run(), if implemented, typically before performing its own implementation steps.

Reimplemented from Analyzer.

References PSUADEDesignCompExp::enforce_input_rules(), PSUADEDesignCompExp::get_parameter_sets(), Iterator::iteratedModel, and Analyzer::pre_run().

core_run()

void core_run ( )

protectedvirtual

core portion of run; implemented by all derived classes and may include pre/post steps in lieu of separate pre/post

Virtual run function for the iterator class hierarchy. All derived classes need to redefine it.

Reimplemented from Iterator.

References Analyzer::evaluate_parameter_sets(), Iterator::iteratedModel, Analyzer::numLSqTerms, and Analyzer::numObjFns.

post_run()

void post_run ( std::ostream &  s )

protectedvirtual

post-run portion of run (optional); verbose to print results; re-implemented by Iterators that can read all Variables/Responses and perform final analysis phase in a standalone way

Post-run phase, which a derived iterator may optionally reimplement; when not present, post-run is likely integrated into run. This is a virtual function; when re-implementing, a derived class must call its nearest parent's post_run(), typically after performing its own implementation steps.

Reimplemented from Analyzer.

References Dakota::abort_handler(), Analyzer::allResponses, Analyzer::allSamples, Model::continuous_lower_bounds(), Model::continuous_upper_bounds(), PSUADEDesignCompExp::enforce_input_rules(), Iterator::iteratedModel, Analyzer::numContinuousVars, Analyzer::numFunctions, PSUADEDesignCompExp::numSamples, and Analyzer::post_run().

num_samples()

size_t num_samples ( ) const

inlineprotectedvirtual

Return current number of evaluation points. Since the calculation of samples, collocation points, etc. might be costly, provide a default implementation here that backs out from the maxEvalConcurrency.

Reimplemented from Analyzer.

References PSUADEDesignCompExp::numSamples.

enforce_input_rules()

void enforce_input_rules ( )

private

enforce sanity checks/modifications for the user input specification

Users may input a variety of quantities, but this function must enforce any restrictions imposed by the sampling algorithms.

References Analyzer::numContinuousVars, PSUADEDesignCompExp::numPartitions, PSUADEDesignCompExp::numSamples, and PSUADEDesignCompExp::varPartitionsSpec.
