Hi, I am
in the process of learning about Jess. Actually I am currently reading
the Jess in Action book and I have a question. In Section 3, there is the
example of the “Tax form advisor”. I have gone through it and
it has answered many questions I had. It has also sparked several new
questions. Please,
would somebody explain this to me: there are quite a few rules defined in
the “Interview” section, some with no “LHS”. According
to the book, “these rules have no patterns and are activated by a call to
reset”. I’m cool with that. My question is, how does
Jess know the order in which these rules get loaded into the Agenda? I
have tried the example many times over, even compared to the output in the book
(pages 183 and 184) and the questions are always asked in the same order. The
first question is the one for the annual income, the next is for the ‘home
office’. The ‘home office’ rule was the last one
defined in the Interview section. So, how does Jess know to ask for ‘request-income’
first, then ‘request-home-office’ followed by ‘charity’
and so on? I realize there are other questions that are qualified by how
much income one has. I am just trying to understand how the non-LHS rules
get queued up. Thank
you, and any info would be greatly appreciated… Joe |
