Previous Projects

The Bowl Championship Series (BCS) ranking system plays a significant role during the end of the college football seaon, as it determines which two teams will compete in the BCS National Championship Game.  Our work investigates the accuracy of the BCS and strives to improve it.
  • We analyzed the accuracy of the BCS computer rankings We use a basic set of game statistics to build a mathematical model used to produce a set of team rankings. We use a more in-depth set of play-by-play statistics to build a model for ranking teams.
Our results can be found here and here. Watch the conference presentation on this work here and some local news coverage here.

Bipartite matching between two source code revisions
Recent work on tracking source locations has focused on tracking lines through multiple revisions of software. In SDiff, we explore a new technique for tracking statements, rather than lines, across multiple revisions of Java source code.   SDiff achieves accuracy comparable with the most accurate line-tracking techniques, while also safely handling all non-executable formatting changes, such as breaking a single statement across many lines, adding or removing whitespace, moving brackets, or re-ordering methods.
