Class solver::Population

A population is a container for several instances of Content_T

Each instance of Content_T is internally wrapped in a Citizen wrapper, which allows setting the desired duplicity count of the contained instance after resampling. These new counts are, however, only applied after a call to resample(). Example: Population std::string population; population.insert("foo"); population.insert("bar"); population.insert("baz"); for (size_t i = 0; i < population.size(); i++) { auto& citizen = population[i]; if (citizen.content() == "foo") citizen.kill() if (citizen.content() == "baz") citizen.spawn(2) } // output before resampling: "foobarbaz" for (size_t i = 0; i < population.size(); i++) { std::cout << population[i].content(); } population.resample(); // output after resampling: "bazbarbazbaz" for (size_t i = 0; i < population.size(); i++) { std::cout << population[i].content(); }

Methods

reserve()

Declaration

void solver::Population<Content_T>::reserve(size_t size)

insert()

Add content to the population (with a count of 1).

Declaration

void solver::Population<Content_T>::insert(Content_T content)

resize()

Declaration

void solver::Population<Content_T>::resize(size_t new_count)

size()

Get the current number of citizens.

This does not consider current counts set on the citizens, so it should be called after resample(), prior to any set_count() on the citizens.

Declaration

size_t solver::Population<Content_T>::size() const

empty()

Check if the population is empty.

Declaration

bool solver::Population<Content_T>::empty()

operator[]()

Positional access to citizens.

They are in no particular order, but the order remains "stable" during resampling.

Declaration

const Citizen&solver::Population<Content_T>::operator[](size_t position) const

operator[]()

Declaration

Citizen&solver::Population<Content_T>::operator[](size_t position)

resample()

Resample the population such that count_ copies of each citizen in the current population are present in the resampled one.

Declaration

void solver::Population<Content_T>::resample()

get_families()

Returns a map describing the sizes of the remaining families.

Declaration

const std::map<FamilyId, size_t>&solver::Population<Content_T>::get_families()

partial_sort()

Declaration

void solver::Population<Content_T>::partial_sort(unsigned solutions_to_sort)

clear()

Declaration

void solver::Population<Content_T>::clear()

clear_cache_pool()

Declaration

void solver::Population<Content_T>::clear_cache_pool()

do_census()

Declaration

void solver::Population<Content_T>::do_census()

create_citizen()

Declaration

void solver::Population<Content_T>::create_citizen(std::unique_ptr<Citizen>&citizen, const Content_T&content)

remove_citizen()

Declaration

void solver::Population<Content_T>::remove_citizen(std::unique_ptr<Citizen>&citizen)
