About

Computational Complexity

Explore fundamental concepts of computational complexity with interactive graphs and live sorting algorithm demonstrations. Developed by academics, this app offers a fun and educational way to visualize algorithmic growth and efficiency.

Highlights
  • Interactive Big-O function graphs
  • Live sorting algorithm demonstrations
  • Visualizes algorithmic growth
  • Source code available on Github
  • Educational tool for computer science
Features
Read full description

This app demonstrates the basic principles of computational complexity. The growth of a few typical Big-O functions are illustrated with an interactive graph, and live demonstrations of sorting algorithms can be run using randomly generated data. This app was developed at SUNY Binghamton, by Prof. Patrick H. Madden. Version 1.1 is an expansion on this, with the assistance a few students (primarily Keith Gardner, and undergrad, and Anthony Canino, an MS grad). We're working on the app as a fun project, and as a way to introduce ACM student group members to iOS programming. The source for the app is available on Github; we'll be adding more algorithms and things, and if you're interested in helping out with the development, let us know! https://github.com/keithgardner2/complexity Yay computational complexity! Yay Hartmanis and Stearns!
