I was inspired by this post on HN, and decided that I could build my own.

This is a pretty rough first effort.

• jarchive - Web scraper for J-Archive. Extracts database of historical jeopardy clues/answers.
• jtextclust - Text clustering routines in R to cluster similar questions.
• jtutor - Django App to quiz players. Designed to be browser/smartphone compatible. Select questions based on learned history (optimized to get player to profitability very quickly).

• Player simulators.
• Profitability estimators.
• Per-player tracking.
• Better optimization model.
