[comp.ai] Needed production system in common lisp

cats@freja.diku.dk (Carl-Lykke Pedersen) (06/07/89)

Is there someone that can tell me if a product exists which serves as an
inference engine/production system capable of foward and backward 
chaining? It must be implemented in common lisp. Please help.


                                 THANKS,
                               cats@diku.dk
