A Call for Papers for:
M-2-M
"Model to Model"
A Workshop
31st March - 1st April 2003 in Marseille, France
Submission Dead line: 1st November 2002
In recent years there has been an explosion of published literature
utilising Multi-Agent-Based Simulation (MABS) to study social,
biological and artificial systems. However, despite the plethora of
novel models and interesting results it is rare that models are
compared, built-on or transferred between researchers. It would seem
there is a dearth of "model-to-model" analysis.
The aim of this workshop is to gather researchers in MABS who are
interested in understanding and furthering the transferability of
knowledge between models and beyond. Although models tend to give very
seductive results, it is not always clear how people who are not the
modeller can interpret or utilise such results - particularly when
building their own models.
Understanding complex systems often seems to necessitate the use of more
than one model. This might be for several different reasons, for
example: different models at varying levels of abstraction might be used
for different purposes. By specifically comparing models a better view
of what modelling brings to the understanding of (real and artificial)
societies may be facilitated.
Comparison of models can be achieved by diverse means that have been
commonly used by researchers to attain validation or to get a better
understanding of others' work, for example:
° Rewriting models that others have described in papers
so as to understand them more deeply and reproduce
the stated results (Axelrod, 1997);
° Composition of models where different scales are
inter-related in a larger model - the results of one
model being used in the other;
° Comparison of different models that announce the same
type of results and trying to see if they actually
produce similar (or the same) results - sometimes
termed "aligning" of models (Axtell et al., 1996);
° Comparison of different models based on their fitness
to a set of data;
° Using one model as a post-hoc summary or abstraction
of another model's results; Constraining the scope
of an existing model to enable more powerful
techniques to be applied in a different
computational framework;
° Using models with different structures and
assumptions to confirm each other's results;
° Determining what to do when two models give results
that contradict each other.
Workshop papers must be based on some comparison of models, as described
above. Papers should therefore deal with at least two agent based
simulation models (with at least one of them already published). The
relationships between the models should be central to the paper and
covered in detail. The models should be presented in enough detail to
allow for the reader to understand the comparative element. Ideally any
new models should be described in sufficient detail for others to be
able to reimplement them. Given these criteria papers may be technical
or theoretical.
