Small Weakly Universal Turing Machines
We give small universal Turing machines with state-symbol pairs of (6, 2), (3, 3) and (2, 4). These machines are weakly universal, which means that they have an infinitely repeate...

Four Small Universal Turing Machines
We present small polynomial time universal Turing machines with state-symbol pairs of (5, 5), (6, 4), (9, 3) and (18, 2). These machines simulate our new variant of tag system, the...

Simulation of a Turing Machine using EndoII Splicing Rules
In this paper we define splicing rules for class II restriction endonucleases and show how a Turing Machine can be simulated using such rules.

Robust Simulations of Turing Machines with Analytic Maps and Flows
In this paper, we show that closed-form analytic maps and flows can simulate Turing machines in an error-robust manner. The maps and ODEs defining the flows are explicitly obtai...

Simulation-Based Security with Inexhaustible Interactive Turing Machines
Recently, there has been much interest in extending models for simulation-based security in such a way that the runtime of protocols may depend on the length of their input. Findi...
