I’ve been working hard on a new search algorithm visualizer, check it out!


Using an HTML5 canvas and async/await, it implements:

  • Random Walk
  • Depth First Search
  • Iterative Deepening
  • Breadth First Search
  • Greedy Best First Search
  • Recursive Best First Search
  • A*

Features include:

  • Variable playback speed / pausing / stepping
  • What you draw is saved in the URL so you can reload the page or share the link (Twitter has a high URL length limit :) )
  • Different heuristics
  • Variable grid/cell size
  • Kind of works on mobile
  • 8-connected search as well as 4-connected
  • You can update the grid in real-time while the algorithm searches (“adversarial search”)

It was tricky working around JavaScript’s single threaded nature, async/await proved to be extremely useful in this project.
