On the Expressiveness of Asynchronous Cellular Automata [chapter]

Benedikt Bollig
2005 Lecture Notes in Computer Science  
We show that a slightly extended version of asynchronous cellular automata, relative to any class of pomsets and dags without autoconcurrency, has the same expressive power as the existential fragment  ...  In doing so, we provide a framework that unifies many approaches to modeling distributed systems such as the models of asynchronous trace automata and communicating finite-state machines.  ...  Statement (1) follows from [1] and (2) follows from [11] and the fact that DAG( Σ) is the language of an ACA relative to DAG(({a}) a∈Σ ).  ...

1995 Mathematical Reviews  
An additive (“totalistic”) cellular automaton (CA) is one in which the local next-state function depends only on the sum of states (regarded as natural numbers) of neighborhood-cells.  ...  The motivation of this paper is to rework a notion of asynchronous automata introduced by Zielonka [RAIRO Inform. Théor.  ...

2000 Mathematical Reviews  
We show that the expressiveness of monadic second-order logic and that of asynchronous cellular automata are different in the class of all pomsets without autoconcurrency.  ...  The universality and the equivalence of asynchronous automata for pomsets are proved to be decidable, but this is shown not to be the case for asynchronous cellular automata.”  ... 

Robustness of Cellular Automata in the Light of Asynchronous Information Transmission [chapter]

Olivier Bouré, Nazim Fatès, Vincent Chevrier
2011 Lecture Notes in Computer Science  
Cellular automata are classically synchronous: all cells are simultaneously updated.  ...  This paper presents a new type of asynchronism, the β-synchronism, where cells still update at each time step but where the transmission of information between cells is disrupted randomly.  ...  This extension is a first step towards a unified view of asynchronism for cellular automata, based on the idea of cell cycles. There exist plenty of other ways the cellular activity can be perturbed.  ...

Probing robustness of cellular automata through variations of asynchronous updating

Olivier Bouré, Nazim Fatès, Vincent Chevrier
2012 Natural Computing  
We then use the novel updating schemes to probe the behaviour of Elementary Cellular Automata, and observe a wide variety of results.  ...  Typically viewed as a deterministic model of spatial computing, cellular automata are here considered as a collective system subject to the noise inherent to natural computing.  ...  Preliminary observations We now apply β-and γ-synchronism to one of the simplest classes of cellular automata, the Elementary Cellular Automata, and compare the resulting behaviours 1 to the dynamics of  ...
