While I'm on the subject of rules engines (which seem to be my main blogging topic currently), I should report that during the last two or three weeks, I took the plunge and expanded (rather a lot) the Wikipedia article of the Rete algorithm.   See http://en.wikipedia.org/wiki/Rete_algorithm.     Originally, I used the text of an explanation I wrote a year or so ago.   I got some kickback on that, with claims of inaccuracy and other claims that the text was too convoluted (what, me write convoluted content - impossible!).   The original text wasn't inaccurate, but it was less comprehensive than it should have been, and lacking clarity in places.  I spent some time last week extensively re-writing and expanding it, and have published the new version.    I’m not sure it’s any easier to read, but it is more complete.  Rete is a specialist subject, but if you are interested in how rules engines like MS BRE work internally, and specifically how they approach the problem of doing efficient combinatorial pattern-based matching of facts to rule conditions, then take a look.   I've added in links to other Wikipedia articles, and I plan at some point to add a few more diagrams.   Being Wikipedia, of course, anyone is free to alter, extend, re-write or even delete the content, so if you're also a Rete-head, please feel free.

You've definitely improved it and made a significant improvement. Don't mind back seat drivers like myself, who are too lazy to actually update wikipedia :)

to be blunt, I'm not sure any change I could make would be readable. I've been told by close friends i often sounds like noise.

Thanks Peter. Your comments are always appreciated. Congratulations on the new job, by the way. 70 hour weeks on rules! My wife would kill me.

Luckily for me, my wife is very understanding. I make it up with exquisite chinese dishes. It's a good thing I'm married, otherwise I doubt there would be any chance of me procreating.
