Computational Social Choice (COMSOC)
COMSOC represents a burgeoning research domain situated at the confluence of artificial intelligence, theoretical computer science, and theoretical economic theory. It focuses primarily on automating the process of optimal collective decision-making through algorithmic methodologies. This course will focus on the following questions: (1) How do different decision-making rules function? (2) What are the key considerations and criteria in designing these decision-making rules? (3) What are the significant combinatorial problems associated with these rules, and are there efficient algorithms to solve them?
