Quoting fischer-michael@cs.yale.edu (Michael Fischer) in article <1993Jan6.033354.4587@cs.yale.edu>: > >: 3) Assuming (2), are there any deterministic problems that have a lower >: complexity for probabilistic Turing machines than deterministic ones? > >: 4) Is is known that there are no such problems? >If I understand your questions, the answers to (2) and (4) are both >trivially "no". What happens if we ask only that the probability that the program fails to complete within the lower time bound tends to zero as the size of the problem tends to infinity? __ _____ \/ o\ Paul Crowley pdc@dcs.ed.ac.uk \\ // /\__/ "I'm the boy without a soul." \X/
