AI A* Pathfinding
Team of 2 Project for DigiPen (CS380)
Experimental A* Pathfinding using Spring-Based Physics for Formations

  • Implemented A* pathfinding.
  • Use of spring-based physics for formations using constraints.
  • Also simple flow field implementation along walls.
  • Formations based on .XML templates.
  • If constraints are too far apart, the constraints will break and remaining objects will form a new formation and pathfind for themselves.
  • Formations will reform if available while objects of different formations are selected.

Engineering Test Projects

Reverse Words
Engineering Test Project
Reverses the words in a text input but not letters

  • Written in F# in Visual Studio 2008
  • Minimal code and optimized for memory and time.
  • Algorithm first splits the input string into a sequence of strings as words with delimiters of spaces and newlines, then uses fold to reverse the sequence, and finally uses a combination of fold and StringBuilder to combine the reversed sequence into a string.

Finds all possible words in a Boggle board within the rules of Boggle

  • Written in C++ in Visual Studio 2008.
  • Includes saving and loading input boards.
  • Optional console for debug and timings.
  • Changeable minimum letter words.
  • Uses the Scrabble Tournament Word List as a dictionary.
  • Dictionary implemented as a trie graph for fast prefix lookup.

Links Configuration
Engineering Test Project
Finds a possible configuration of 2 links, end to end, with one end at a target


  • Written in C++ in Visual Studio 2008 using DirectX SDK (June 2010).
  • Optional console for debug and timings.
  • Can move the camera in spherical coordinates around origin.
  • Can move target and start point of first link using keyboard.
  • Uses a closed-form solution to the link configuration.
