Getting Started

Prerequisites

• Python 3
• Required libraries: numpy, pandas, scikit-learn, matplotlib

Installation

1. Clone the repository:

https://github.com/parvvaresh/cluster_ga
cd cluster_ga

2. Install the required dependencies:

pip install -r requirements.txt

Usage

Run the genetic_clustering.py script to execute the genetic clustering algorithm on the provided dataset. Make sure to update the script with your dataset or use the default Iris dataset.

python3 test_iris.py

Algorithm Overview

The genetic clustering algorithm consists of the following components:

Genetic Class

Defines the genetic operations such as mutation, generation, and fitness calculation.

Cluster Class

Manages the clustering process, including the initialization of populations, evolution, and convergence.

Main Script

Utilizes the genetic and clustering classes to run the algorithm on a given dataset.

Parameters

• size_population: Number of individuals in the population.
• goal: The desired fitness score to achieve.
• repeat: Number of generations to run the algorithm.
• is_mutation: Boolean flag to enable or disable mutation.

Results

The script outputs the progress of the algorithm, including the generation number and the fitness score achieved. Additionally, a plot of the fitness scores over generations is displayed at the end of the execution.
