Computability Part 7: Machine Implementation Practicalities

Tag systems are Turing-complete. I was wondering if there is any easy way to create tag systems that simulate finite automata. So create tag systems that recognize languages, e.g. by having

essentially consisting of two parts, Classical Computability Theory and Gener-alized Computability Theory. In Chapter 1 we use a Kleene-style introduction to the class of computable functions,

Proving universality of larger CAs (with larger neighbourhood or more states) is much easier and you can even get rid of the intermediate tag-system simulation, so you could

I’ve read that it is known that tag systems in TS(2,2), that is, with two symbols and deletion number $2$, are decidable.. I suppose I’m asking for clarification on what that means

Stephen Wolfram uses modern tools to explore Emil Post’s tag system. Possible states, cycle structure, random walks, number theory, other tag systems and ties to his own work.

CT is an extremely minimalist programming language that can simulate arbitrary tag systems, and is therefore Turing-complete. A program consists simply of a string of 3

That means that lambda calculus can compute anything that a Turing machine can compute, thus the two systems have the same computability power. In general, if a system

This question arose in the context of tag-like systems, specifically Bitwise Cyclic Tag (BCT). Consider the following discrete dynamical system: Let $\mathbb{B} = \{\mathtt{0},

Emil Post’s tag system problem is the question of whether or not a tag system $\\{N=3, P(0)=00, P(1)=1101\\}$ has a configuration, simulation of which will never halt or end

Cyclic tag systems can be made to duplicate the halting/non-halting behavior of whatever system they simulate (e.g., halting whenever a simulated „standard“ TM halts), so I’ve posted an
