Re: how to bind a variable with multislots in the LHS?

Hi Pedro,

I really meant to reply to your previous post earlier but I completely
forgot, I am sorry. I ran into this (or at least a very similar)
problem a few months ago when I was comparing CLIPS and Lisa.

The problem, as you have already figured out, lies in that there are
no multislots in Lisa.

This will make it difficult for you to do a direct translation of the
puzzle. If you assert a list in a slot you can either match it as-is
or provide your own comparison function. See
http://commentsarelies.blogspot.com/2007/10/another-clips-and-lisa-comparison.html
for an example.

Personally I think you should define a template for each of the
implied facts, not only is it more readable, it is also faster.
Mutlislots are terribly slow in CLIPS. I love them because they allow
me to express a pattern match very clearly and concisely but I hate
them because whenever I pour in a few thousand facts matching such a
rule I might as well call it a day.

Good luck
Johan Lindberg
