The Multi-Agent Systems group at the University of Groningen has a
broad research spectrum.

We use multi-agent simulation as a tool to study market dynamics,
diffusion and transition processes. Agents are equipped with different
needs and decision heuristics such as social comparision,
deliberation, imitation etc. Simulation experiments provide a
perspective on the behavioural dynamics that play a role in certain
systems. Empirical research is targeted at the empirical validation of
these dynamics.

Simulations are also used for the modelling of group processes,
especially processes where collaboration problems such as (partially)
conflicting goals may occur. The way in which features of social
networks, such as friendship and trust, influence the collaboration of
task groups is of special interest. In particular, we model how social
networks and cooperative behaviour evolve through interdependent
social learning of group members. With this, we study the conditions
under which network structures emerge that foster or hamper the
solution of cooperation problems between interdependent agents.

Finally, formal, prescriptive multi-agent research is carried out in
order to build and facilitate cooperation in groups of agents. Special
attention goes to the modelling of (collective) intentions and
commitments, and how reconfiguration could take place in a changing
environment. In the Anita project, we create a multi-agent system
which dynamically manages access control of very sensitive information.

The members of our group regularly participate in program committees
of international agent-related conferences, and also organise
workshops on agent research, such as SIMSOC
( and FAMAS
