M2M2
Second "Model to Model" workshop:
Comparing and combining agent-based models with each other,  
and with other models  
Workshop to be held on 14 and 15 September 2004, Valladolid, Spain
In association with the second ESSA conference

Aims and Topic

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 second M2M workshop, M2M2, is aimed at gathering researchers in MABS who 
are interested in understanding and furthering the transferability of knowledge 
between Multi-Agent Based Simulation models and beyond. As in the first M2M 
workshop (Marseille, France, March-April 2003), papers are invited reporting 
comparisons and validations involving two or more models, at least one being an 
agent-based model. 
Understanding complex systems often seems to necessitate the use of more than 
one 
model.  By specifically comparing models a better view of what modelling brings 
to 
the understanding of (real and artificial) societies may be facilitated. The 
union of two 
or more models with apparently incompatible levels of abstraction, comparisons 
of 
results from related studies, and the description of model findings in ways 
allowing 
others to check and replicate them, all require the development of methods that 
improve rigor and reproducibility.
Approaches of interest include but are not limited to: 
*       Rewriting models that others have described in papers so as to 
understand 
them more deeply and reproduce the stated results;
*       Composition of models where different scales are inter-related in a 
larger 
model - the results of one model being used in the other; 
*       Aligning of models: a comparison of different models that announce the 
same 
type of results, so as to evaluate their actual similarities;
*       Comparison of different models based on their fitness to a set of data, 
accumulated through field studies or experiments; 
*       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. 
*       Constructing and using taxonomies or description schemas for use in 
comparing or combining MABS models.

At the first M2M workshop, two specific issues were addressed: 
(1) How can different multi-agent models best be compared? (What kinds of 
comparison are feasible, and how can comparisons be useful?) 
(2) Is it possible to transmit the structure of a model and its results among 
researchers 
through papers, or should we look for other means of transmission? 

The meeting proved that the issues at stake seemed fundamental for many 
practitioners. Most papers addressed the replication of models through 
alignment: 
comparing different level of aggregation describing the same system and 
evaluating 
the differences and similarities between centralised models and distributed 
ones; 
checking the influence of rationality at different result levels, or trying to 
integrate 
several forms of rationality. Other papers addressed the issue of replication 
and 
concluded here that there are considerable conceptual and practical 
difficulties in 
replicating others' work, but doing so can be most enlightening. 

A number of papers have been published in a resulting special issue in
JASSS (http://jasss.soc.surrey.ac.uk/6/4/5.html). Authors wishing to
submit a paper to M2M2 are advised to refer to this issue,  although
it is not representative of all possible approaches on the
topic. Following M2M, this new workshop will hopefully bring together
an international community and produce new frameworks to look at
agent-based simulation results. 

Date and Venue

The M2M2 workshop will be held in association with the 2004 ESSA conference, as 
a 
1 1/2 day workshop on the 14th and 15th of September 2004 in Valladolid, Spain. 
The same format will be kept for presentation, 45 minutes being given to each 
participant to present their paper.

Call for Papers

Send paper by email by April 15, to:
     Nick Gotts (address@hidden) or 
     Guillaume Deffuant (address@hidden). 
Papers should be sized between 10 and 20 pages and will be selected through 
peer 
review. Contributors wishing to submit demos, models, or other material with 
their 
paper are invited to contact a member of the organising committee.
