RealLife: The continuum limit of Larger than Life cellular automata

Marcus Pivato
2007 Theoretical Computer Science  
We also show that the 'life forms' (fixed points, periodic orbits, and propagating structures) of LtL CA converge to life forms of RealLife.  ...  We prove a conjecture of Evans: as their radius grows to infinity, LtL CA converge to a 'continuum limit' Euclidean automaton, which we call 'RealLife'.  ...  In Section 2 we show that RealLife EA are the continuum limits of suitable sequences of Larger than Life CA of increasing radius, and that a suitable converging sequence of still lifes (resp. oscillators  ...

Real-Time Traffic Simulation Using Cellular Automata [article]

Christopher S. Applegate, Stephen D. Laycock, Andy M. Day
2010 Computer Graphics and Visual Computing  
We test the performance of our model using a 500 x 500m2 area of a real city, and demonstrate that our model can simulate over 600 vehicles at real-time frame-rates (greater than 80 percent network density  ...  We distribute cells at regular intervals throughout the graph, which are used as discrete vehicle locations in our traffic model.  ...  bound by the larger of the two computation times.  ...

Lenia: Biology of Artificial Life

Bert Wang-Chak Chan
2019 Complex Systems  
They differ from other cellular automata patterns in being geometric, metameric, fuzzy, resilient, adaptive and rule generic.  ...  A broad survey of the life forms is provided and categorized into a hierarchical taxonomy, and their distribution is mapped in the parameter hyperspace.  ...  Acknowledgments I would like to thank David Ha, Sam Kriegman, Tim Hutton, Kyrre Glette, Pierre-Yves Oudeyer, Lana Sinapayen and the anonymous reviewer for valuable discussions, suggestions and insights  ...

Tourism and Simulacrum: The Computational Economy of Algorithmic Destinations

Bernard Lew Shian Loong
2014 Procedia - Social and Behavioral Sciences  
Utilizing rule sets that embody destination growth dynamics and visitor behavioural norms, seeding points in a cellular automata model (CA) were grown into algorithmic destinations.  ...  Seen in this light, the museumification of Venice and the proliferation of its simulacrum, such as the Venetian Hotel in Macao and Venice-themed hotels across the globe, are prefigures and archetypes of  ...  Fig. 1 provides an illustration of this two facets of rules through a game of chess and its analogue in cellular automata (CA).  ...

Virtual Creature Morphology ‐ A Review

G. Lai, F.F. Leymarie, W. Latham, T. Arita, R. Suzuki
2021 Computer graphics forum (Print)  
We also include a historical perspective, with information on methods such as cellular automata, L-systems and a focus on earlier pioneers in the field.  ...  We present a review of methods for procedurally generating the morphology of virtual creatures. We include a range of methods, with the main groups being from ALife over art to video games.  ...  Cellular Automata Conway's cellular automaton Game of Life (GoL) from 1970 [Gar70] has an evocative life-like look, that when simulated, reminds us of cells in a petri dish.  ...

Relating the dynamics of road traffic in a stochastic cellular automaton to a macroscopic first-order model [article]

Sven Maerivoet, Steven Logghe, Ben Immers, Bart De Moor
2005 arXiv   pre-print
In this paper, we describe a relation between a microscopic traffic cellular automaton (TCA) model (i.e., the stochastic TCA model of Nagel and Schreckenberg) and the macroscopic first-order hydrodynamic  ...  Our results indicate that, in the presence of noise, the capacity flows in the derived fundamental diagram are overestimations of those of the STCA model.  ...  In this section, we briefly recapitulate a special class of microscopic models, i.e., traffic cellular automata (TCA) models.  ...

The effectiveness of mathematics in physics

Jane Frances McDonnell
The two parts focus on different aspects of the problem and should be viewed as stages on the way to a final formulation.  ...  In this thesis I argue that many problems in the philosophy of science and mathematics (in particular, the unreasonable effectiveness of mathematics in physics) can only be addressed within a broader metaphysical  ...  It seems that the world could have been describable in terms of the mathematics of cellular automata or Newtonian mechanics, for example.  ...

Philosophical foundations for information fusion : towards a social-process paradigm

Andrew Samuel Dawson
In the past decade the focus of research into artificial intelligence (AI) has moved from individual agents to multi-agent systems (MAS).  ...  The social interpretation of MAS has also been embraced by social scientists interested in developing MAS-based simulations of society.  ...  I relate the story in the introduction, but my thanks to Brendan for shaking me out of my slumbers with respect to the field of artificial intelligence.  ...
