Member Function Documentation

assign()

void edal::Patch::assign	(	size_t	n,
		const Individual &	founder
	)

Fill this patch with the same number of females and males.

Parameters

n	The number of inital individuals in this patch
founder	The individual to be copied

emplace_back()

void edal::Patch::emplace_back ( Individual &&  ind )

inline

Add an individual to this patch.

Parameters

ind	New individual to add

empty()

bool edal::Patch::empty ( ) const

inline

Returns

Whether this patch is empty or not

make_destinations()

std::vector< std::pair< unsigned int, unsigned int > > edal::Patch::make_destinations	(	size_t	n,
		size_t	row,
		size_t	col,
		size_t	num_rows,
		size_t	num_cols
	)		const

Change row/col with probability \(m\) = Individual::MIGRATION_RATE_.

With probability \( m > 0 \), each offspring becomes a "migrant." Each migrant goes to one of the 8 neighboring patches. For patches at the boundary, the probability \( m \) is reduced according to the number of neighbors they have.

size()

size_t edal::Patch::size ( ) const

inline

Returns

The number of individuals in this patch
