Mathematical modeling of electoral systems: analysis, evaluation, optimization. In memory of Bruno Simeone (1945-2010)

摘要

This volume of the Annals of Operations Research is dedicated to the memory of our dear friend and colleague Bruno Simeone (1945-2010). It collects a selection of papers on mathematical modeling of electoral systems. In his long and fruitful academic and scientific career, Bruno Simeone's interest in the study of electoral systems was driven by the absence of a sound appraisal of the mechanics of electoral formulae in the intense debate over electoral reform in Italy and the awareness of the contradictions and flaws of the (past and current) Italian Electoral Law. Since 1993 he studied different electoral problems with a mathematical approach-from gerrymandering to proportional electoral formulae, passing through governability and representation issues, always highlighting the constructive solutions that this can lead to and the practical policy guidance that could be derived from this kind of analysis.
