Overview

Package floatarr provides a genotype type that is a slice of float64 values. It also provides functions for reproduction using these genotypes.

Types

type Genotype

type Genotype []float64

Genotype is a genotype that is a slice of float64 values.

func NewGenotype

func NewGenotype(size int, std float64) Genotype

NewGenotype creates a new genotype with the given size, where each value is a random float64 with a normal distribution with the given standard deviation.

func (Genotype) Clone

func (f64s Genotype) Clone() any

Clone returns a new genotype that is a copy of this genotype.

func (Genotype) PointCrossoverWith

func (f64s Genotype) PointCrossoverWith(other goevo.PointCrossoverable) goevo.PointCrossoverable

PointCrossoverWith returns a new genotype that is a combination of this genotype and the other genotype.

func (Genotype) UniformStdMutate

func (f64s Genotype) UniformStdMutate(probPerLocus, mutStd float64)

UniformStdMutate modifies the genotype by adding a random value from a normal distribution to each value with the given probability and standard deviation.

type UniformStdReproduction

type UniformStdReproduction struct {
	// The probability of mutating each locus
	MutateProbability float64
	// The standard deviation for the mutation
	MutateStd float64
}

UniformStdReproduction is a reproduction strategy for Float64sGenotype. It performs crossover and mutation.

func (*UniformStdReproduction) NumParents

func (r *UniformStdReproduction) NumParents() int

NumParents returns 2, as this reproduction strategy requires 2 parents.

func (*UniformStdReproduction) Reproduce

func (r *UniformStdReproduction) Reproduce(gs []Genotype) Genotype

Reproduce creates a new genotype by crossing over and mutating the given genotypes.
