Member Function Documentation

add()

void FT::Pop::Population::add

(

Individual &

ind

)

adds a program to the population.

adds ind to individuals, giving it an open location and bookeeping.

Definition at line 112 of file population.cc.

init()

void FT::Pop::Population::init	(	const Individual &	starting_model,
		const Parameters &	params,
		bool	random = false,
		string	filename = ""
	)

initialize population of programs with a starting model and/or from file

create random programs in the population, seeded by initial model weights and potentially saved models

Definition at line 38 of file population.cc.

load()

void FT::Pop::Population::load

(

string

filename

)

Definition at line 165 of file population.cc.

operator[]() [1/2]

const Individual & FT::Pop::Population::operator[]

(

size_t

i

)

Definition at line 35 of file population.cc.

operator[]() [2/2]

const Individual FT::Pop::Population::operator[]

(

size_t

i

)

const

setting and getting from individuals vector

Definition at line 33 of file population.cc.

print_eqns()

string FT::Pop::Population::print_eqns	(	bool	just_offspring = false,
		string	sep = "\n"
	)

return population equations.

Definition at line 121 of file population.cc.

resize()

void FT::Pop::Population::resize

(

int

pop_size

)

update individual vector size

save()

void FT::Pop::Population::save

(

string

filename

)

Definition at line 150 of file population.cc.

size()

int FT::Pop::Population::size

(

)

returns population size

Definition at line 31 of file population.cc.

sorted_front()

vector< size_t > FT::Pop::Population::sorted_front

(

unsigned

rank = 1

)

return complexity-sorted Pareto front indices.

Definition at line 135 of file population.cc.

update()

void FT::Pop::Population::update

(

vector< size_t >

survivors

)

reduce programs to the indices in survivors.

cull population down to survivor indices.
