Streamlit-Based GUI for EvoloPy Optimization Suite

[deepak-158]

This pull request introduces a full-featured Graphical User Interface (GUI) built with Streamlit for running and visualizing optimizers from the EvoloPy library. The goal is to provide an interactive and beginner-friendly interface that allows users to easily select optimizers, benchmark functions, and hyperparameters—while also viewing real-time convergence data.

✨ Key Features

🎛️ GUI Functionality

• Developed using Streamlit for easy interaction and deployment.
• Sidebar for user inputs:
  • Optimizer selection (multi-select)
  • Benchmark function selection (multi-select)
  • Population size input
  • Iterations input
• Main window displays:
  • Best solution (Alpha, Beta, Gamma)
  • Execution time
  • Tabular data of fitness values
  • Real-time convergence graph using Plotly
  • Convergence rate per iteration (as a percentage bar chart)

📈 Visualization

• Convergence Plot: Line graph of fitness over iterations
• Convergence Rate Plot: Bar chart showing rate of improvement per iteration
• Comparison Plot: Overlays all optimizer-function results for visual benchmarking

📊 Data Processing

• Extracts best individuals and computes convergence rates
• Uses pandas and numpy for tabular data manipulation

📦 Dependencies

• streamlit
• numpy
• pandas
• plotly

---

🧪 Example Usage

Run the following command in your terminal to start the app:

streamlit run gui_app2.py

---

🛠️ Files Modified/Added

• gui_app2.py: Main application script for Streamlit GUI
• No core EvoloPy logic modified; this is a non-intrusive extension

---

🤝 Motivation

This contribution makes it easier for users, especially beginners and researchers, to:

• Explore how different optimizers perform
• Analyze convergence behavior visually
• Reduce barrier to entry for working with metaheuristic algorithms

🚀 Future Improvements (Optional)

• Support for custom benchmark functions (user-defined)
• Add download options for plots and results
• Save experiment results as CSV or JSON
• Add logging window or error trace panel
