Interactive Operating System Algorithms Simulation Platform

Interactive desktop app for visualizing CPU scheduling and page replacement algorithms.

Quick Start

Install Library

pip install matplotlib

Run the Simulator

python tkinter_simulator.py

What's Inside

CPU Scheduling: FCFS • SJF • Round Robin • Priority • MLFQ • EDF
Page Replacement: FIFO • LRU • Optimal • Clock
Advanced: Algorithm Duel • Hybrid Simulation • Workload Generator

Features

  1. Visual Results - Gantt charts and frame state diagrams
  2. Algorithm Comparison - Side-by-side performance analysis
  3. Real-time Scheduling - EDF with deadline visualization
  4. Workload Generator - Create realistic test scenarios
  5. No Web Server - Pure desktop app, works offline

Example Input

CPU: 1,0,5,2,10    (PID, Arrival, Burst, Priority, Deadline)
Page: 1,2,3,4,1,2,5,1,2,3,4,5

Try the Demos

python demos/demo_cpu_scheduling.py      # Basic algorithms
python demos/demo_algorithm_duel.py      # Compare algorithms  
python demos/demo_hybrid_workload.py     # Advanced features

Perfect for students, educators, and anyone learning operating systems! 🎓
