There are no theoretical limits on the size of a Jess program -- the only hard limit is available memory. 32-bit JVMs usually limit you to a ~2GB heap; given 250,000 rules, that's 8KB per rule, which is far more than enough assuming average rule characteristics. Note that Jess' performance is independent of the total number of rules; it has a logarithmic dependence on the number of simultaneously activated rules. > Also, my knowledge of > rule-based systems > is limited to a few AI books, Can someone recommend another book, web page > etc..
