Detailed Description

Base class for the model class hierarchy.

The Model class is the base class for one of the primary class hierarchies in DAKOTA. The model hierarchy contains a set of variables, an interface, and a set of responses, and an iterator operates on the model to map the variables into responses using the interface. For memory efficiency and enhanced polymorphism, the model hierarchy employs the "letter/envelope idiom" (see Coplien "Advanced C++", p. 133), for which the base class (Model) serves as the envelope and one of the derived classes (selected in Model::get_model()) serves as the letter.

Constructor & Destructor Documentation

◆ Model() [1/5]

Model ( )

default constructor

The default constructor is used in vector<Model> instantiations and for default initialization of Model objects. modelRep is NULL in this case (a populated problem_db is needed to build a meaningful Model object).

◆ Model() [2/5]

Model ( ProblemDescDB & problem_db )

standard constructor for envelope

Used for envelope instantiations within strategy constructors. Envelope constructor only needs to extract enough data to properly execute get_model, since Model(BaseConstructor, problem_db) builds the actual base class data for the derived models.

References Dakota::abort_handler(), and Model::modelRep.

◆ Model() [3/5]

Model ( const Model & model )

copy constructor

Copy constructor manages sharing of modelRep.

◆ Model() [4/5]

Model	(	BaseConstructor	,
		ProblemDescDB &	problem_db
	)

protected

constructor initializing the base class part of letter classes (BaseConstructor overloading avoids infinite recursion in the derived class constructors - Coplien, p. 139)

This constructor builds the base class data for all inherited models. get_model() instantiates a derived class and the derived class selects this base class constructor in its initialization list (to avoid the recursion of the base class constructor calling get_model() again). Since the letter IS the representation, its representation pointer is set to NULL.

References Dakota::abort_handler(), Model::currentResponse, Dakota::expand_for_fields_sdv(), Model::fdGradStepSize, Model::fdHessByFnStepSize, Model::fdHessByGradStepSize, ProblemDescDB::get_rv(), ProblemDescDB::get_sa(), Model::gradIdNumerical, Model::gradientType, Model::hessianType, Model::hessIdNumerical, Model::initialize_distribution(), Model::initialize_distribution_parameters(), Model::modelId, Model::mvDist, Model::num_primary_fns(), Model::primaryRespFnSense, Model::primaryRespFnWts, Model::probDescDB, Response::shared_data(), Dakota::strbegins(), Dakota::strtolower(), and Model::user_auto_id().

◆ Model() [5/5]

Model	(	LightWtBaseConstructor	,
		ProblemDescDB &	problem_db = `dummy_db`,
		ParallelLibrary &	parallel_lib = `dummy_lib`
	)

protected

constructor initializing base class for recast model instances

This constructor also builds the base class data for inherited models. However, it is used for derived models which are instantiated on the fly. Therefore it only initializes a small subset of attributes.

◆ update_from_subordinate_model()

void update_from_subordinate_model ( size_t depth = SZ_MAX )

virtual

propagate vars/labels/bounds/targets from the bottom up

used only for instantiate-on-the-fly model recursions (all RecastModel instantiations and alternate DataFitSurrModel instantiations). Simulation, Hierarchical, and Nested Models do not redefine the function since they do not support instantiate-on-the-fly. This means that the recursion will stop as soon as it encounters a Model that was instantiated normally, which is appropriate since ProblemDescDB-constructed Models use top-down information flow and do not require bottom-up updating.

NestedModels: a subIterator can support message passing parallelism, but not asynch local.
DataFitSurrModels: while asynch evals on approximations will work due to some added bookkeeping, avoiding them is preferable.

◆ evaluation_cache()

bool evaluation_cache ( bool recurse_flag = true ) const

◆ subordinate_models()

ModelList & subordinate_models ( bool recurse_flag = true )

return the sub-models in nested and surrogate models

since modelList is built with list insertions (using envelope copies), these models may not be used for model.assign_rep() since this operation must be performed on the original envelope object. They may, however, be used for letter-based operations (including assign_rep() on letter contents such as an interface).

void init_communicators	(	ParLevLIter	pl_iter,

		bool	recurse_flag = `true`
	)

allocate communicator partitions for a model and store configuration in modelPCIterMap

The init_communicators() and derived_init_communicators() functions are stuctured to avoid performing the messageLengths estimation more than once. init_communicators() (not virtual) performs the estimation and then forwards the results to derived_init_communicators (virtual) which uses the data in different contexts.

◆ init_serial()

void init_serial ( )

◆ estimate_message_lengths()

void estimate_message_lengths ( )

estimate messageLengths for a model

This functionality has been pulled out of init_communicators() and defined separately so that it may be used in those cases when messageLengths is needed but model.init_communicators() is not called, e.g., for the master processor in the self-scheduling of a concurrent iterator strategy.

◆ assign_rep()

void assign_rep ( std::shared_ptr< Model > model_rep )

replaces existing letter with a new one

The assign_rep() function is used for publishing derived class letters to existing envelopes, as opposed to sharing representations among multiple envelopes (in particular, assign_rep is passed a letter object and operator= is passed an envelope object).

Use case assumes the incoming letter is instantiated on the fly and has no envelope. This case is modeled after get_model(): a letter is dynamically allocated and passed into assign_rep (its memory management is passed over to the envelope).

If the letter happens to be managed by another envelope, it will persist as long as the last envelope referencing it.

int derivative_concurrency ( ) const

return the gradient concurrency for use in parallel configuration logic

This function assumes derivatives with respect to the active continuous variables. Therefore, concurrency with respect to the inactive continuous variables is not captured.

◆ user_auto_id()

String user_auto_id ( )

staticprotected

return the next available model ID for no-ID user methods

Rationale: The parser allows multiple user-specified models with empty (unspecified) ID. However, only a single Model with empty ID can be constructed (if it's the only one present, or the "last one parsed"). Therefore decided to prefer NO_MODEL_ID over NO_MODEL_ID_<num> for (some) consistency with interface NO_ID convention. MODEL was inserted in the middle to distinguish "anonymous" MODELS from methods and interfaces in the hdf5 output. Note that this function is not used to name recast models; see their constructors for how its done.

◆ no_spec_id()

String no_spec_id ( )

staticprotected

return the next available model ID for on-the-fly methods

Rationale: For now NOSPEC_MODEL_ID_ is chosen due to historical id="NO_SPECIFICATION" used for internally-constructed Models. Longer-term, consider auto-generating an ID that includes the context from which the method is constructed, e.g., the parent method or model's ID, together with its name. Note that this function is not used to name recast models; see their constructors for how its done.

evaluate numerical gradients using finite differences. This routine is selected with "method_source dakota" (the default method_source) in the numerical gradient specification.

Estimate derivatives by computing finite difference gradients, finite difference Hessians, and/or quasi-Newton Hessians. The total number of finite difference evaluations is returned for use by synchronize() to track response arrays, and it could be used to improve management of max_function_evaluations within the iterators.

overlay results to update a response object

Overlay the initial_map_response with numerically estimated new_fn_grads and new_fn_hessians to populate new_response as governed by asv vectors. Quasi-Newton secant Hessian updates are also performed here, since this is where the gradient data needed for the updates is first consolidated. Convenience function used by estimate_derivatives() for the synchronous case and by synchronize_derivatives() for the asynchronous case.

Coordinates usage of estimate_derivatives() calls based on asv_in.

Splits asv_in total request into map_asv_out, fd_grad_asv_out, fd_hess_asv_out, and quasi_hess_asv_out as governed by the responses specification. If the returned use_est_deriv is true, then these asv outputs are used by estimate_derivatives() for the initial map, finite difference gradient evals, finite difference Hessian evals, and quasi-Hessian updates, respectively. If the returned use_est_deriv is false, then only map_asv_out is used.
