Universality of Graph-controlled Leftist Insertion-deletion Systems with Two Statessymbol at a time. We start by introducing extended rules, in which the contexts may be specified as regular expressions, instead of fixed words. We then prove that leftist systems with such extended rules and two-state graph control can simulate any arbitrary 2-tag system. Finally, we show how our c

An Intrinsically Universal Family of Causal Graph Dynamics time-steps, with respect to two physics-like symmetries: causality (there exists a bounded speed of information propagation) and shift-invariance (the rewriting acts everywhere the same). Intrinsic universality is the ability of the instance of a model to simulate all other instances, while preserv

Universality in Infinite Petri Nets expanding traversals of the cell array. One net is obtained via direct simulation of the cellular automaton while the other net simulates a Turing machine, which simulates the cellular automaton. They use cell models of 21 and 14 nodes, respectively, and simulate the cellular automaton in polynomia
