Researchers have developed a novel approach using SMT and Lean to synthesize and verify voting methods on infinite domains, a significant advancement over traditional finite-domain SAT solvers. This method addresses the challenge of finding social choice procedures that satisfy specific criteria, particularly for scenarios with an arbitrary number of voters but a fixed set of candidates. The study presents a possibility theorem for four key voting theory axioms: the Condorcet winner and loser criteria, positive involvement, and resolvability, demonstrating that such a method exists for four candidates, contrary to previous findings for more candidates.
