Turing Automata and Graph Machines [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
Indexed monoidal algebras are introduced as an equivalent structure for self-dual compact closed categories, and a coherence theorem is proved for the category of such algebras.

A theory of consciousness from a theoretical computer science perspective: Insights from the Conscious Turing Machine [PDF]

open access: yesProc Natl Acad Sci U S A, 2021
Significance This paper provides evidence that a theoretical computer science (TCS) perspective can add to our understanding of consciousness by providing a simple framework for employing tools from computational complexity theory and machine learning ...

On Halting Process of Quantum Turing Machine [PDF]

open access: green, 2005
We prove that there is no algorithm to tell whether an arbitrarily constructed Quantum Turing Machine has same time steps for different branches of computation. We, hence, can not avoid the notion of halting to be probabilistic in Quantum Turing Machine.

Decision Problems For Turing Machines [PDF]

open access: yesInformation Processing Letters, 2009
We answer two questions posed by Castro and Cucker, giving the exact complexities of two decision problems about cardinalities of omega-languages of Turing machines.

On-line turing machine recognition

open access: bronzeInformation and Control, 1968
Let U(n) be a monotone increasing function which is real-time computable, {if442-1}. Then it is possible to describe a set of words AU such that(1)AU is recognizable within the time bound T(n) = C1.U(n), for suitable {itC1};(2)If M is an on-line Turing machine which recognizes the set of words AU, then τM(n) > CM.U}(n) for infinitely many values of n ...

Models of Quantum Turing Machines [PDF]

open access: greenFortschritte der Physik, 1999
Quantum Turing machines are discussed and reviewed in this paper. Most of the paper is concerned with processes defined by a step operator $T$ that is used to construct a Hamiltonian $H$ according to Feynman's prescription. Differences between these models and the models of Deutsch are discussed and reviewed.

Infinite time Turing machines [PDF]

open access: greenJournal of Symbolic Logic, 2000
AbstractWe extend in a natural way the operation of Turing machines to infinite ordinal time, and investigate the resulting supertask theory of computability and decidability on the reals. Everyset. for example, is decidable by such machines, and the semi-decidable sets form a portion of thesets.

Simulating Turing machines on Maurer machines

open access: bronzeJournal of Applied Logic, 2007
AbstractIn a previous paper, we used Maurer machines to model and analyse micro-architectures. In the current paper, we investigate the connections between Turing machines and Maurer machines with the purpose to gain an insight into computability issues relating to Maurer machines. We introduce ways to simulate Turing machines on a Maurer machine which,

Reactive Turing machines [PDF]

open access: yesInformation and Computation, 2011
We propose reactive Turing machines (RTMs), extending classical Turing machines with a process-theoretical notion of interaction, and use it to define a notion of executable transition system. We show that every computable transition system with a bounded branching degree is simulated modulo divergence-preserving branching bisimilarity by an RTM, and ...
