WebbAs we will de ne them, these Turing machines are allowed to give incorrect outputs, or even loop forever. Due to their random nature, we will prove several theorems from probability theory to aid our analysis. 10.1 Probabilistic Turing Machines A probabilistic Turing machine is a Turing machine Mthat has two transition functions 0 and 1. At each In computational complexity theory, a branch of computer science, bounded-error probabilistic polynomial time (BPP) is the class of decision problems solvable by a probabilistic Turing machine in polynomial time with an error probability bounded by 1/3 for all instances. BPP is one of the largest practical classes of problems, meaning most problems of interest in BPP have efficient probabilistic algorithms that can be run quickly on real modern machines. BPP also contains P, th… WebbEquivalently, probabilistic Turing machines can be viewed as deterministic machines with two inputs: the ordinary input, and an auxiliary "random input". One then considers the probability distributions deﬁned by ﬁxing the ﬁrst input and letting the auxiliary input assume all possible values with equal probability. middletown roofing louisville

Webb1 nov. 1980 · Introduction In [7], it was shown that every language accepted by an S(n) tape-bounded probabilistic Turing machine can be accepted by a deterministic Turing machine within tape O(S(n )6). In this note, we extend this result by showing that S(n ) tape-bounded probabilistic machine transducers; not just probabilistic acceptors, can be … WebbDefined probabilistic Turing machines and the class BPP.

WebbIn general, if you have a probabilistic Turing machine P solving some decision problem, you can always simulate it deterministically by running P for every possible value of the randomness and outputting the majority answer of P. Therefore, no probabilistic Turing machine can solve an undecidable decision problem. Webbcomputing machines now known as Turing machines. These machines may be used to characterize a class of functions known as the partially recursive functions [3]. As it …
