Conceptualizing Machines in an Eco-Cognitive Perspective

open access: yesPhilosophies, 2022
Eco-cognitive computationalism explores computing in context, adhering to some of the key ideas presented by modern cognitive science perspectives on embodied, situated, and distributed cognition.

Computing halting probabilities from other halting probabilities [PDF]

open access: yes, 2016
The halting probability of a Turing machine is the probability that the machine will halt if it starts with a random stream written on its one-way input tape.

Chromatin computation. [PDF]

open access: yesPLoS ONE, 2012
In living cells, DNA is packaged along with protein and RNA into chromatin. Chemical modifications to nucleotides and histone proteins are added, removed and recognized by multi-functional molecular complexes.

Small universal Turing machines

open access: yesTheoretical Computer Science, 1996
AbstractLet UTM(m, n) be the class of universal Turing machine with m states and n symbols. Universal Turing machines are proved to exist in the following classes: UTM(24,2), UTM(10,3), UTM(7,4), UTM(5,5), UTM(4,6), UTM(3,10) and UTM(2,18).

A universal Turing machine [PDF]

open access: yes, 1993
The aim of this paper is to give an example of a universal Turing machine, which is somewhat small. To get a small universal Turing machine a common constructions would go through simulating tag system (see Minsky 1967). The universal machine here simulate two-symbol Turing machines directly.

Self-reproducing Coins as Universal Turing Machine [PDF]

open access: yes, 2018
Turing-completeness of smart contract languages in blockchain systems is often associated with a variety of language features (such as loops). In opposite, we show that Turing-completeness of a blockchain system can be achieved through unwinding the recursive calls between multiple transactions and blocks instead of using a single one.

Computers and chess masters: The role of AI in transforming elite human performance

open access: yesBritish Journal of Psychology, EarlyView.
Abstract Advances in Artificial Intelligence (AI) have made significant strides in recent years, often supplementing rather than replacing human performance. The extent of their assistance at the highest levels of human performance remains unclear. We analyse over 11.6 million decisions of elite chess players, a domain commonly used as a testbed for AI

Completeness of the Dynamics of the Attributes Values of Data in the Database DIM

open access: yesМоделирование и анализ информационных систем, 2015
This paper is devoted to justifying the possibility of DBMS DIM usage and its interaction mechanism as an algorithmically complete implementation of an objectdynamic model.

A Swiss Pocket Knife for Computability [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
This research is about operational- and complexity-oriented aspects of classical foundations of computability theory. The approach is to re-examine some classical theorems and constructions, but with new criteria for success that are natural from a ...

Color Image Encryption Algorithm Based on a Chaotic Model Using the Modular Discrete Derivative and Langton’s Ant

open access: yesMathematics, 2023
In this work, a color image encryption and decryption algorithm for digital images is presented. It is based on the modular discrete derivative (MDD), a novel technique to encrypt images and efficiently hide visual information. In addition, Langton’s ant,
