Reinforcement Learning and Artificial Intelligence (RLAI)
	Tile coding development page

The ambition of this page is to provide the development versions of the various implementations and reference manual for tiles, and to be a place to discuss development issues for tiles.

---

Issues:

• Testing code to ensure that the tiles code works correctly
• Timing comparisons between the python, lisp and c versions, as well as a version where python calls c
• Maybe a visual learning interface for tiles? (like the fa demo)

Tasks:

• Develop regression/progression tests
• Test python version
• Update lisp version
• Test lisp version
• Update c version
• Test c version
• Create version where python calls c
• Test python calling c version
• Do comparison timings between all versions
• Update external documentation
• Develop simple examples for users
• Develop visual tool for learning/teaching?

The latest version has been uploaded on the main Tiles page January 25, 2005.

Further issues:

• The fancytiles routines - are the calling sequences for these appropriate? Are the transformations correct? Are these routines useful?
• The tilesdemo - is this visual tool useful? How can it be improved?
• Is there a better way to test correctness than using the tilesdemo?
  
• The timing shows that the load versions of the Python->C tiles code are very slow. Can this be improved?
