Detailed Description

Wrapper class for the FSUDace QMC/CVT library.

The FSUDesignCompExp class provides a wrapper for FSUDace, a C++ design of experiments library from Florida State University. This class uses quasi Monte Carlo (QMC) and Centroidal Voronoi Tesselation (CVT) methods 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

FSUDesignCompExp

(

Model &

model

)

primary constructor for building a standard DACE iterator

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

FSUDesignCompExp	(	Model &	model,
		int	samples,
		int	seed,
		const String &	sampling_method
	)

alternate constructor for building a DACE iterator on-the-fly

This alternate constructor is used for instantiations on-the-fly, using only the incoming data. No problem description database queries are used.

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.
