Detailed Description

COLINApplication is a DAKOTA class that is derived from COLIN's Application hierarchy. It redefines a variety of virtual COLIN functions to use the corresponding DAKOTA functions. This is a more flexible algorithm library interfacing approach than can be obtained with the function pointer approaches used by NPSOLOptimizer and SNLLOptimizer.

void set_problem ( Model model)
utilib::Any spawn_evaluation_impl ( const utilib::Any &  domain,
const colin::AppRequest::request_map_t &  requests,
utilib::seed_t &  seed 
)
virtual

Schedule one or more requests at specified domain point, returning a DAKOTA-specific evaluation tracking ID.

Schedule one or more requests at specified domain point, returning a DAKOTA-specific evaluation tracking ID. This is only called by COLIN's concurrent evaluator, which is only instantiated when the Model supports asynch evals. The domain point is guaranteed to be compatible with data type specified by map_domain(...)

References COLINApplication::colin_request_to_dakota_request(), Model::evaluate_nowait(), Model::evaluation_id(), and COLINApplication::iteratedModel.

bool evaluation_available ( )
virtual

Check to see if there are any function values ready to be collected.

Check to see if any asynchronous evaluations have finished. This is only called by COLIN's concurrent evaluator, which is only instantiated when the Model supports asynch evals.

References COLINApplication::blockingSynch, COLINApplication::dakota_responses, COLINApplication::iteratedModel, Model::synchronize(), and Model::synchronize_nowait().

void perform_evaluation_impl ( const utilib::Any &  domain,
const colin::AppRequest::request_map_t &  requests,
utilib::seed_t &  seed,
colin::AppResponse::response_map_t &  colin_responses 
)
virtual

Perform a function evaluation at t given point.

Perform an evaluation at a specified domain point. Wait for and return the response. This is only called by COLIN's serial evaluator, which is only instantiated when the Model does not support asynch evals. The domain point is guaranteed to be compatible with data type specified by map_domain(...)

utilib::Any collect_evaluation_impl ( colin::AppResponse::response_map_t &  colin_responses,
utilib::seed_t &  seed 
)
virtual

Collect a completed evaluation from DAKOTA.

Collect the next completed evaluation from DAKOTA. Always returns the evalid of the response returned.

)
virtual
void dakota_response_to_colin_response ( const Response dakota_response,

)
virtual

Gelper function to convert evaluation response data from DAKOTA structures to COLIN structures.

Map DAKOTA objective and constraint values to COLIN response.

bool map_domain ( const utilib::Any &  src,
utilib::Any &  native,
bool  forward = true 
) const
virtual

Map the domain point into data type desired by this application context.

Map the domain point into data type desired by this application context (utilib::MixedIntVars). This data type can be exposed from the Any &domain presented to spawn and collect.
