Struct Generate 

pub struct Generate<InputParameters, ReturnValue, T: Callable<InputParameters, ReturnValue>, U: Callable<InputParameters, ReturnValue> + Mutate + Crossover> { /* private fields */ }

A genetic algorithm for finding good functions

Implementations

impl<InputParameters: Vals, ReturnValue: Vals, T: Callable<InputParameters, ReturnValue>, U: Callable<InputParameters, ReturnValue> + Mutate + Crossover + Clone + Disassemble> Generate<InputParameters, ReturnValue, T, U>

pub fn new(target_function: T) -> Self

Constructs a new GeneticSearch

pub fn population_size(&mut self, population_size: usize)

Sets the population size

pub fn crossover_rate(&mut self, crossover_rate: f64)

Sets the crossover_rate (the default is 2.0)

pub fn mutation_rate(&mut self, mutation_rate: f64)

Sets the mutation_rate (the default is 1.0)

pub fn selection(&mut self)

Keeps the best specimens and removes the worst ones

pub fn next_generation(&mut self)

computes the next generation of the search

pub fn search(&mut self) -> U

Returns one specimen having a score of 0.0, removing it from the population. If no such specimen exists, then .next_generation() is called until one is found.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
