AIMA-Java 1.5.1-Chp15-Rewrite

All of the algorithms from Chapter 15 have been rewritten:
  • 15.4 Forward-Backward (3 implementations provided)
  • 15.6 Fixed-Lag-Smoothing 
  • 15.17 Particle-Filtering  
Added an Iterator interface and supporting methods to CategoricalDistribution and Factor. ProbabilityTable.Iterator removed getPostIterateValue() method from API due to not being general. Fixed Issue 63 - all compilation warnings have been resolved or suppressed where appropriate for now. Documentation clean up.

Enjoy!

Michael Stampone officially Joins the Team

Michael has been doing great work updating the project's Javadoc and plans to do some games development (chess and checkers) possibly using JOGL to demonstrate some of the core algorithms. He now has commit privileges on the project.

Demo Applications now run from Google Code

Read a couple of articles related to sending out content from a Subversion repository:

http://code.google.com/p/rdv/wiki/JavaWebStart
http://stuffthathappens.com/blog/2007/11/09/howto-publish-javadoc-on-google-code/

and realized I needed to update the svn:mime-type on the relevant .html, .css and .jnlp files to their correct values. All appears to be working now so to get to the main demo page from now on just go to:


http://aima-java.googlecode.com/svn/trunk/aima-all/release/aima3ejavademos.html

Enjoy!
