+# Python Video Selection Optimizer: High-Performance Genetic Algorithm
+
+[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/adhishagc/Genetic-Algorithm-using-Python-Example/blob/master/Video_Playlist_Optimizer_GA.ipynb)
+
+An advanced optimization tool designed to solve the **Constrained Video Selection Problem** using **Genetic Algorithms (GA)**. This project demonstrates how to maximize total playback duration within a fixed storage capacity (e.g., fitting the best playlist on a 4.5GB drive).
+
+## Overview
+
+This repository implements a robust Genetic Algorithm in Python to optimize multi-variable selection problems. Specifically, it tackles a variation of the **0/1 Knapsack Problem** where the goal is to maximize the "value" (video duration) while staying under a "weight" limit (file size).
+
+### Key Optimization Features:
+- **Selection Methods**: Rank Selection, Roulette Wheel, and Tournament Selection.
+- **Crossover Operators**: Generalized N-Point Crossover and Uniform Crossover.
+- **Mutation**: Adaptive Bit-Flip Mutation.
+- **Survival Policy**: Elitism with FIFO replacement to ensure the best solutions are never lost.
+
+## Performance Results
+
+The algorithm was tested on a sample dataset of 10 high-definition video files with a storage constraint of **4500 MB**.
+
+| Metric | Result |
+|--------|--------|
+| **Total Optimized Duration** | **549 Minutes** |
+| **Storage Capacity Used** | **3950 / 4500 MB** |
+| **Algorithm Generations** | 100 |
+| **Population Size** | 50 |
+
+The results show a highly efficient selection that utilizes ~88% of the available storage while maximizing entertainment value, significantly outperforming random selection methods.
+
+### Convergence and Optimization Plots
+
+The following plots illustrate the algorithm's performance during the optimization process:
+
+#### 1. Fitness Convergence
+This plot shows how the fitness of the population improves over generations, indicating successful convergence towards an optimal solution.

+
+#### 2. Duration Optimization
+The total playback duration is maximized over time, reaching a peak of 549 minutes.

+
+#### 3. Storage Size Constraints
+The algorithm ensures that the selected videos stay within the 4500 MB limit (indicated by the orange threshold line).

+## About the Subject Matter
+Genetic Algorithms are search heuristics inspired by Charles Darwin’s theory of natural evolution. They are widely used in data science, logistics, and AI to find near-optimal solutions to complex optimization problems that are computationally expensive for traditional algorithms.
