pyreda

pyreda is a Python library for implementing and running Genetic Algorithms (GAs). It provides an easy-to-use interface to configure and execute GAs with customizable parameters for selection, crossover, and mutation.

Features

• Customizable fitness functions
• Support for tournament selection
• One-point crossover
• Bit-flip mutation
• Configurable mutation rates and number of generations

Installation

You can install pyreda via pip:

pip install pyreda

Usage

Here’s a basic example of how to use pyreda to run a genetic algorithm:

import SimpleGA from pyreda

from pyreda import SimpleGA
import numpy as np

Define a custom fitness function

# Example: Sum of all genes
def custom_fitness(individual):
	return np.sum(individual)

Create an instance of the SimpleGA class

ga = SimpleGA.SimpleGA(
	population_size=10,       # Size of the population
	gene_length=5,             # Length of each individual
	fitness_function=custom_fitness,  # Fitness function to evaluate individuals
	mutation_rate=0.01,        # Mutation rate
	generations=20            # Number of generations to evolve
)

Parameters:

population_size: Number of individuals in the population.
gene_length: Length of the individual’s gene sequence.
fitness_function: Function to evaluate the fitness of an individual.
mutation_rate: Probability of mutation for each gene.
generations: Number of generations for the algorithm to run.

Run the genetic algorithm

ga.run()
