Constructor & Destructor Documentation

MlpIndividual::MlpIndividual

(

)

Construct uninitialized; only for reading values very soon.

MlpIndividual::MlpIndividual	(	const MlpObjectives &	mobj,
		unique_ptr< jymlp::Mlp >	imlp,
		shared_ptr< Dataset >	ids
	)

Constructor by taking ownership of a jyu::Mlp instance and shared ownership of a dataset.

All of these are required for meaningful computations.

Member Function Documentation

void MlpIndividual::crossWith

(

MlpIndividual &

other

)

[protected, virtual]

This is specific to MlpIndividual.

FIXME: Probably to go away.

Implements Individual.

void MlpIndividual::evaluate

(

)

[virtual]

Evaluate objective functions.

Is to be called before getting values, if any operators have been applied. The concrete derived class must assign objective values when this is called.

Implements Individual.

vector< double > MlpIndividual::getTrace

(

)

[virtual]

Get measures that are interesting in post-run tracing; subclasses would know which measures are of importance.

By default, the objectives are returned as a vector object.

Reimplemented from Individual.

void MlpIndividual::impl_from_stream

(

istream &

repr

)

[protected, virtual]

"Crowding" value/dist. (e.g. NSGA-II)

Read the actual (concrete) representation from a stream.

Implements Individual.

void MlpIndividual::impl_to_stream

(

ostream &

repr

)

[protected, virtual]

Write the actual (concrete) representation to a stream.

Implements Individual.

void MlpIndividual::improve

(

mt19937 *

mt

)

[virtual]

Apply memetic improvement operator(s).

Up to the concrete class.

Implements Individual.

void MlpIndividual::mutate

(

)

[virtual]

Apply evolutionary mutation operator(s).

Up to the concrete class.

Implements Individual.
