Firefly Algorithm --- Implementation of Firefly algorithm in Python

About

This package implements a nature-inspired algorithm for optimization called Firefly Algorithm (FA) in Python programming language.

Installation:

Install FireflyAlgorithm with pip:

pip install fireflyalgorithm

To install FireflyAlgorithm on Fedora, use:

dnf install python-fireflyalgorithm

To install FireflyAlgorithm on Arch Linux, please use an AUR helper:

$ yay -Syyu python-fireflyalgorithm

Usage:

from fireflyalgorithm import FireflyAlgorithm
from fireflyalgorithm.problems import sphere

FA = FireflyAlgorithm()
best = FA.run(function=sphere, dim=10, lb=-5, ub=5, max_evals=10000)

print(best)

Test functions

In the fireflyalgorithm.problems module, you can find the implementations of 33 popular optimization test problems. Additionally, the module provides a utility function, get_problem, that allows you to retrieve a specific optimization problem function by providing its name as a string:

from fireflyalgorithm.problems import get_problem

# same as from fireflyalgorithm.problems import rosenbrock
rosenbrock = get_problem('rosenbrock')

Command line interface

The package also comes with a simple command line interface which allows you to evaluate the algorithm on several popular test functions

firefly-algorithm -h

usage: firefly-algorithm [-h] --problem PROBLEM -d DIMENSION -l LOWER -u UPPER -nfes MAX_EVALS [-r RUNS] [--pop-size POP_SIZE] [--alpha ALPHA] [--beta-min BETA_MIN] [--gamma GAMMA] [--seed SEED]

Evaluate the Firefly Algorithm on one or more test functions

options:
  -h, --help            show this help message and exit
  --problem PROBLEM     Test problem to evaluate
  -d DIMENSION, --dimension DIMENSION
                        Dimension of the problem
  -l LOWER, --lower LOWER
                        Lower bounds of the problem
  -u UPPER, --upper UPPER
                        Upper bounds of the problem
  -nfes MAX_EVALS, --max-evals MAX_EVALS
                        Max number of fitness function evaluations
  -r RUNS, --runs RUNS  Number of runs of the algorithm
  --pop-size POP_SIZE   Population size
  --alpha ALPHA         Randomness strength
  --beta-min BETA_MIN   Attractiveness constant
  --gamma GAMMA         Absorption coefficient
  --seed SEED           Seed for the random number generator

Note: The CLI script can also run as a python module (python -m niaarm ...)
