Member Function Documentation

void FgenppPopulation::Initialize	(	int	population_size,
		int	individual_size_in_bits,
		int	data_element_size
	)

Initialize an FgenppPopulation. This does the same things as fgen_create(). The FgenppPopulation must be instantiated.

Definition at line 181 of file fgenpp.cpp.

void FgenppPopulation::Destroy

(

)

Destroy data structures associated with a population. The FgenppPopulation class itself is not deallocated.

Definition at line 201 of file fgenpp.cpp.

void FgenppPopulation::GenerationCallback

(

int

generation

)

[virtual]

The generation callback method. Usually overridden in a derived sub-class.

Definition at line 59 of file fgenpp.cpp.

double FgenppPopulation::CalculateFitness

(

const unsigned char *

bitstring

)

[virtual]

The calculate error method. The default one does nothing. It must be overridden by a derived sub-class.

Definition at line 68 of file fgenpp.cpp.

void FgenppPopulation::Seed

(

unsigned char *

bitstring

)

[virtual]

The seed method. The default is the random bitstring seeding operator SeedBitstringRandom. Can be overridden by a derived sub-class.

Definition at line 76 of file fgenpp.cpp.

void FgenppPopulation::Mutate	(	const unsigned char *	parent,
		unsigned char *	child
	)		[virtual]

The mutate method. The default is mutation per bit plus macro mutation for bitstring (MutatePerBitPlusMacroMutation). Can be overridden by a derived sub-class.

Definition at line 85 of file fgenpp.cpp.

void FgenppPopulation::Crossover	(	const unsigned char *	parent1,
		const unsigned char *	parent2,
		unsigned char *	child1,
		unsigned char *	child2
	)		[virtual]

The crossover method. The default is two-point bitwise crossover for bitstrings (CrossoverTwoPointPerBit). Can be overridden in a derived sub-class.

Definition at line 94 of file fgenpp.cpp.
