A "round-robin" is a method used in tournaments and competitions where each participant competes against every other participant. This format ensures that all players or teams have an equal opportunity to compete, making it fair and comprehensive. It is commonly used in sports, games, and academic competitions. In a round-robin tournament, points are typically awarded for wins, losses, and ties. At the end of the competition, the participant with the most points is declared the winner. This system is often contrasted with knockout formats, where participants are eliminated after a loss, such as in single-elimination tournaments.
