Re: golog in minipicolisp
Hi Alex, If I had taken yours and Yiorgos advice and read these two articles *before* doing the swi-prolog to pilog translation it might have cleared some things up I was guessing about. http://en.wikipedia.org/wiki/Situation_calculus http://drops.dagstuhl.de/opus/volltexte/2010/2631/pdf/10081.Ferrein.2631.pdf Sill some issues there, but I am very optimistic. Starting at 120kb or so, people can embed golog with minipicolisp/pilog into systems. And I have an application that will be fun, I think, to use this approach in. :-) Cheers, Doug --- On Sun, 6/26/11, Alexander Burger wrote: > From: Alexander Burger > Subject: Re: golog in minipicolisp > To: picolisp@software-lab.de > Date: Sunday, June 26, 2011, 11:50 AM > On Sun, Jun 26, 2011 at 01:44:33AM > -0700, Doug Snead wrote: > > (It looks not so bad, once I studied golog_swi.pl a > bit more.

Re: golog in minipicolisp ?
Yiorgos, Alexander: Thanks for the info. Unfortunately, not so straightforward as I had hoped.

Concerning the implementations in "gologinterpreter.pl" and "golog_swi.pl": The operator definitions with 'op' are not available in Pilog, though I could imagine they can be emulated. I must say that for me personally it is difficult to understand what that code does, especially without knowing Golog. I have problems to read "real" Prolog, as I never used it. What does the '-' syntax mean? Negation? But there is also 'not' ... There are many predicates I don't know, e.g. '?', 'proc', 'star', 'while', 'pi', 'primitive_action' etc. Are they built-in? Perhaps someone with a better knowledge of Prolog (Clemens?) can help? Cheers, - Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
Re: golog in minipicolisp ?
GOLOG is described in: Levesque, H. J., Reiter, R., Lespérance, Y., Lin, F., & Scherl, R. B. (1997). GOLOG: A Logic Programming Language for Dynamic Domains. Journal of Logic Programming, 31(1-3), 59-83 It is based on the Situation Calculus. Since Lisp and the Situation Calculus are closely related, it might be better to work directly in picolisp rather than trying to adapt a Prolog implementation into pilog.
