Oracle Turing machines faced with the verification problem

چکیده

The main current issue about hypercomputation concern the following thesis: it is physically possible to build a hypercomputation model. To prove this thesis, one possible strategy could be to physically build an oracle Turing machine. More precisely, it is about finding a physical theory where a hypercomputation model will be able to use some external information from nature. Such an information could be regarded as an oracle that provide an additional element in order to go beyond Turing machines limits. However, there is a recurring epistemological problem about the physical construction of an oracle Turing machine. This problem called “verification problem” may be worded as follows: if we assume we have such a hypercomputation model physically built, it would be impossible to verify that this model is able to compute a non Turing-computable function. In this paper I will propose an analysis of the verification problem in order to show that it does not explicitly dispute the strategy about a physical construction of an oracle Turing machine.

Some improvements in fuzzy turing machines

In this paper, we improve some previous definitions of fuzzy-type Turing machines to obtain degrees of accepting and rejecting in a computational manner. We apply a BFS-based search method and some level’s upper bounds to propose a computational process in calculating degrees of accepting and rejecting. Next, we introduce the class of Extended Fuzzy Turing Machines equipped with indeterminacy s...

Prefix-like Complexities of Finite and Infinite Sequences on Generalized Turing Machines

Generalized Turing machines (GTMs) are a variant of non-halting Turing machines, by computational power similar to machines with the oracle for the halting problem. GTMs allow a definition of a kind of descriptive (Kolmogorov) complexity that is uniform for finite and infinite sequences. There are several natural modifications of the definition (as there are several monotone complexities). This...

Betti numbers of finitely presented groups and very rapidly growing functions

Define the length of a finite presentation of a group G as the sum of lengths of all relators plus the number of generators. How large can be the kth Betti number bk(G) = rank Hk(G) providing that G has length ≤ N and bk(G) is finite? We prove that for every k ≥ 3 the maximum bk(N) of kth Betti numbers of all such groups is an extremely rapidly growing function of N . It grows faster that all f...

ITCS : CCT 09 : Computational Complexity Theory Mar 18 , 2009 Lecture 7

In the previous lectures, we have introduced the concept of deterministic oracle Turing machines. The concept of non-deterministic oracle Turing machines is just a direct extension of that to the non-deterministic case. To be precise, a non-deterministic oracle Turing machine (sometimes abbreviated to “oracle NTM”) is just like a deterministic oracle TM, but with a non-deterministic transition ...

The Log Space Oracle Hierarchy Collapses DRAFT

The polynomial time hierarchy of Meyer and Stockmeyer has several equivalent characterizations — in particular it can be defined either in terms of polynomial time oracle Turing machines [Sto76], or in terms of polynomial time alternating Turing machines where the number of alternations is finitely bounded [CKS81]. One of the most important open questions in the area is whether or not this hier...
