## Abstract

Tournaments are commonly used to select winning alternatives in scenarios involving pairwise comparisons such as sports competitions and political elections. This survey discusses recent developments in two major lines of work—tournament solutions and single-elimination tournaments—with a focus on how computational social choice has brought new frameworks and perspectives into these decades-old studies.
