Detailed Description

Derived model class which performs a complete sub-iterator execution within every evaluation of the model.

The NestedModel class nests a sub-iterator execution within every model evaluation. This capability is most commonly used for optimization under uncertainty, in which a nondeterministic iterator is executed on every optimization function evaluation. The NestedModel also contains an optional interface, for portions of the model evaluation which are independent from the sub-iterator, and a set of mappings for combining sub-iterator and optional interface data into a top level response for the model.

void derived_evaluate ( const ActiveSet set)
protectedvirtual

portion of evaluate() specific to NestedModel

Update subModel's inactive variables with active variables from currentVariables, compute the optional interface and sub-iterator responses, and map these to the total model response.

Reimplemented from Model.

const IntResponseMap & derived_synchronize ( )

short local_eval_synchronization ( )

return optionalInterface synchronization setting

Used in setting Model::asynchEvalFlag. subModel synchronization is used for setting asynchEvalFlag within subModel.

Reimplemented from Model.

References Interface::asynch_local_evaluation_concurrency(), Interface::interface_synchronization(), NestedModel::optInterfacePointer, and NestedModel::optionalInterface.

int local_eval_concurrency ( )

return optionalInterface asynchronous evaluation concurrency

Used in setting Model::evaluationCapacity. subModel concurrency is used for setting evaluationCapacity within subModel.

Reimplemented from Model.

bool derived_master_overload ( ) const

flag which prevents overloading the master with a multiprocessor evaluation (forwarded to optionalInterface)

Derived master overload for subModel is handled separately in subModel.evaluate() within subIterator.run().

Reimplemented from Model.

References Iterator::is_null(), Interface::iterator_eval_dedicated_master(), IteratorScheduler::iteratorScheduling, Interface::multi_proc_eval(), NestedModel::optInterfacePointer, NestedModel::optionalInterface, IteratorScheduler::procsPerIterator, NestedModel::subIterator, and NestedModel::subIteratorSched.

void derived_init_communicators ( ParLevLIter  pl_iter,
int  max_eval_concurrency,
bool  recurse_flag = true 
)
protectedvirtual
int derived_evaluation_id ( ) const
inlineprotectedvirtual

Return the current evaluation id for the NestedModel.

return the top level nested evaluation count. To get the lower level eval count, the subModel must be explicitly queried. This is consistent with the eval counter definitions in surrogate models.

Reimplemented from Model.

void response_mapping ( const Response opt_interface_response,
const Response sub_iterator_response,
Response mapped_response 
)
inlineprivate

combine the response from the optional interface evaluation with the response from the sub-iteration using the primaryCoeffs/secondaryCoeffs mappings to create the total response for the model

In the OUU case,
optionalInterface fns = {f}, {g} (deterministic primary functions, constraints)
subIterator fns       = {S}      (UQ response statistics)

Problem formulation for mapped functions:
                  minimize    {f} + [W]{S}
                  subject to  {g_l} <= {g}    <= {g_u}
                              {a_l} <= [A]{S} <= {a_u}
                              {g}    == {g_t}
                              [A]{S} == {a_t}

where [W] is the primary_mapping_matrix user input (primaryRespCoeffs class attribute), [A] is the secondary_mapping_matrix user input (secondaryRespCoeffs class attribute), {{g_l},{a_l}} are the top level inequality constraint lower bounds, {{g_u},{a_u}} are the top level inequality constraint upper bounds, and {{g_t},{a_t}} are the top level equality constraint targets.

NOTE: optionalInterface/subIterator primary fns (obj/lsq/generic fns) overlap but optionalInterface/subIterator secondary fns (ineq/eq constraints) do not. The [W] matrix can be specified so as to allow

  • some purely deterministic primary functions and some combined: [W] filled and [W].num_rows() < {f}.length() [combined first] or [W].num_rows() == {f}.length() and [W] contains rows of zeros [combined last]
  • some combined and some purely stochastic primary functions: [W] filled and [W].num_rows() > {f}.length()
  • separate deterministic and stochastic primary functions: [W].num_rows() > {f}.length() and [W] contains {f}.length() rows of zeros.

If the need arises, could change constraint definition to allow overlap as well: {g_l} <= {g} + [A]{S} <= {g_u} with [A] usage the same as for [W] above.

In the UOO case, things are simpler, just compute statistics of each optimization response function: [W] = [I], {f}/{g}/[A] are empty.
