Otwieranie i wypełnianie puszki Pandory - stawianie czoła wyzwaniom symulacji agentowej [Opening and filling Pandora's box - addressing agent-based simulation challenges] Harko Verhagen (Department of Computer and Systems Sciences, Stockholm University, Sweden) Developing reliable agent-based simulation models for, e.g., policy makers requires grounding of the agents and their interaction in relevant theories and conceptual models, as well as, in relevant empirical data. In different collaborations I have worked on some of these aspects and will focus on two in particular: (i) a contextual action framework for computational agents trying to encompass different decision-making models and theories, and (ii) conventional and unconventional ways of gathering empirical data. Following this, I will focus on different ways games and agent-based models can enhance each other in such conquests.
