Foreword
Cellular Automata (CA), about to enter their fifties, are coming of age, seen by the
breadth and quality of CA-related research carried out worldwide, as well as by
the appearance of interesting applications to real world problems. The papers
collected in this book, presented at ACRI 98 (Third Conference on Cellular
Automata for Research and Industry - 7-9 October 1998), further demonstrate the
vitality of this line ofresearch.
Until some years ago, a researcher interested in dynamical modelling of spatially
extended systems had only one language at his disposal, namely that of the partial
differential equations (PDE). These are wonderful tools to use when an analytical
solution can be found or a perturbative approach can provide a good
approximation of the observed phenomena. The use of digital computers has
enormously expanded the explanatory and predictive power of partial differential
equations by allowing one to treat cases which had been outside the scope of a
"pen and pencil" approach. However, it has also opened up a way to new
formalisms which are able to describe interesting phenomena and are, at the same
time, well-suited for digital simulation.
Among these formalisms are Cellular Automata, which have noble origins (dating
back to von Neumann's effort at understanding the logic of self reproduction) and
a fairly long history. The interest for cellular automata grew in the 80's, when it
was shown that they can be both an alternative to partial differential equations for
the description of extended physical systems and a precious tool for exploring the
features of complex, nonlinear systems.
Moreover, cellular automata are well-suited for parallel computers (it has been
said that they are "embarrassingly easy" to parallelize). The growing importance
of parallel computing models have provided a further reason of interest in this
field.
Within this framework, several efforts in the creation and implementation of CA
based computational models for the simulation of complex phenomena yielded
very heterogeneous working teams, allowing new trans-disciplinary approaches to
become real and alive. The peculiarity of the model, and the available
technological supports it requires offer a possible scenario where problems,
methods, solutions coming from different knowledge places could meet. It is not
difficult to appreciate the variety of competencies involved in projects whose basic
feature is this conceptual and computational approach.
It is interesting to note that many exciting works developed within the Cellular
Automata community do not strictly adhere to the original definition of what a
cellular automaton is, i.e. a fully homogeneous one where all the cells have the
same transition function, whose state space is discrete and, usually, comprises just
VI
a few different states. In dealing with interesting applications to physical,
biological, and social problems, the model has been expanded to include
continuous state space and inhomogeneity; we regard this as an enrichment of the
cellular automata approach, whose basic feature is a division of a (possibly
abstract) space in discrete cells, rather than as a weakness of the present efforts.
It should be stressed, as well as noted in this volume, that there are now some
working examples of applications of Cellular Automata to real world problems,
not solely to laboratory or toy cases. This may be a major step towards increased
diffusion of this approach.
We would like to acknowledge the Comune di Trieste for their collaboration in
organizing ACRI 98, SIS SA, for their support and for hosting the conference, and
the support we received from other institutions, namely the University of Milan,
Montecatini and illycaffe.
We wish to thank Giancarlo Mauri for his advice and cooperation in the
organization of this event. We would like to express our gratitude to Stefano
Fantoni and the members of the organizing committee for their efforts and the
program committee members for their excellent reviewing work.
