The model of the mind this implies is a digital computer with a random component. But even if this random component is truly random rather than pseudorandom, you could always emulate it with a branching algorithm that explores every possible case. It might be computationally very expensive, but given enough memory and enough time it could be done. -- Stathis Papaioannou --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
