ILOG the first to post solution to Albert Enistein's puzzle on ORF 2009


Daniel Selman was the third to solve and first to post to ORF 2009 a solution to Einstein's Puzzle for ORF 2009. He did it using ILOG's Optimization software (and some help from some friends) and I'm sure Albert would not have approved. the first two entries (NOT programmers) solved it in 20 minutes with only paper and pencil.

New Algorithm From Dr. Charles Forgy


See for the write up on the new algorithm from Dr. Forgy to replace the Rete 2 / Rete III algorithm. Also, we will have a new benchmark just to test that one and others, the WaltzDB-200 later this year. Enjoy...

Rulebase Expertise


AA is off to a screaming good start - congratulations to Rolando Hernandez for NOT following the lead of so many blogs by making it the sameo-sameo kind of blog but more of a all-things-to-all-people kind of blogosphere where everyone can be involved.
