To take most recent book I read years ago on the subject, I'll summarize some parts of [koomen]'s notation (see below).

  • An agent is an entity able to communicate over a port
  • communication happens when a port has a label and another port has the complementary label
  • When agent A and B have ports x and x_ (complementary) they communicate by def. which is called internal action, and the event is denoted by tau.
  • a behaviour equation (E1,E2,..) algebraically defines a part of the behaviour of an agent (A,B..).

Does anyone know of a logical reasoning in tcl package, I guess like prolog does, so a proof mechanism, and maybe a exploration mechanism ?

It's been a long time after I scored my 'formal logic' advanced university course after 3 attempts, and I was fed up with trying, but it was kind of fun to play formal sherlock holmes on the computer...
