This year's seminar covered the modelling of complex systems that are of interest in the social sciences. In an effort to offer pedagogical notes, each topic is comprehensively described and some practical exercises are proposed. This helps introduce non-experts to novel advances in statistical physics and to the creative use of computers in scientific research, as well as to serve as a work of reference for teachers, students and researchers.
