Abstract Recent advancements in Intelligent Transportation Systems have endowed
vehicles with autonomous driving capabilities as well as V2X communication. Vehicular …

We investigate the possibility of strategic voting in approval-based multiwinner rules. In
particular, we define three axiomatic properties that guarantee resilience to certain forms of …

Recently, the winner determination problem of minimax ap-proval committee (or referenda)
