LabMAg is a R&D unit dedicated to computational models of agents, hosted at the Faculty of Sciences of the University of Lisbon (FCUL). LabMAg integrates researchers from FCUL, Universidade de Évora, ISCTE and IST/UTL. LabMAg is one of the founder institutions of the Institute for Complexity Sciences (ICC). The research directions of this unit cover the increasing role of physical, biophysical and social models of agents, within the Computing Sciences. Three main ideas are explored, namely the fact that a) these models have computational power, b) these models have structure/form that can be replicated by computation, and c) these models may be used as metaphors in real problem solving.
