Modelling is a necessary tool to represent, analyse and discuss aspects or ideas related to complex systems. With this in mind, teaching science based on the elaboration of models is widely accepted in the academic community. A relatively new methodology of modelling exists with a different philosophy and perspective from the classic and continuous models used up usually, the so-called agent-based models (ABMs). The general aim of the work is to make this kind of discrete modelling well-known, so that ABMs may be incorporated progressively into the academic curricula, complementing other existing modelling strategies.
