Algorithm Visualizer

An interactive sorting algorithm visualizer built with C#, now featuring a modern WPF-based GUI. This application provides an intuitive way to learn and understand how various sorting algorithms work through real-time visualizations.

Features

• Algorithms Supported:
  • Bubble Sort
  • Quick Sort
  • Merge Sort
  • Selection Sort
  • Heap Sort
  • Insertion Sort
• Dynamic Visualization:
  • Bars represent the array elements.
  • Colors:
    • Gray: Default state.
    • Red: Comparing elements.
    • GreenYellow: Selected or currently active element.
• Interactive Controls:
  • Start and stop buttons for controlling the execution.
  • Algorithm selection via a dropdown menu.
• Customizable Execution Speed:
  • Modify the delay globally to adjust visualization speed.

Technology Stack

• Frontend: Windows Presentation Foundation (WPF)
• Backend: C# (.NET)
• Other Tools:
  • LINQ for array manipulations.
  • Multithreading with Task and CancellationToken for smooth execution and interrupt handling.

How It Works

1. Launch the application: A WPF window with a dropdown for algorithm selection and Start/Stop buttons will appear.
2. Choose an algorithm: Select your desired sorting algorithm from the dropdown menu.
3. Click "Start": Watch the algorithm dynamically sort a randomized array of integers.
4. Stop or restart: Use the Stop button to interrupt and reset the visualization.

Preview

Main Interface

• VisualizerCanvas: Displays the array as bars.
• Controls: Dropdown to select algorithms, and buttons to start or stop execution.

---

Future Improvements

• Add more sorting algorithms (e.g., Radix Sort, Shell Sort).
• Implement array size customization.
• Provide detailed step-by-step textual explanations for each algorithm.
