Example of a round-robin tournament with 10 participants. A round-robin tournament or all-play-all tournament is a competition format in which each contestant meets every other participant, usually in turn. [1] [2] A round-robin contrasts with an elimination tournament, wherein participants are eliminated after a certain number of wins or losses.
A Round Robin preemptive scheduling example with quantum=3. Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing. [1] [2] As the term is generally used, time slices (also known as time quanta) [3] are assigned to each process in equal portions and in circular order, handling all processes without priority (also known as cyclic executive).
One common method of logically implementing the fair-share scheduling strategy is to recursively apply the round-robin scheduling strategy at each level of abstraction (processes, users, groups, etc.) The time quantum required by round-robin is arbitrary, as any equal division of time will produce the same results.
A standard round-robin tournament is used, in which all teams play each other once. Because the number of total games increases quadratically with respect to the number of teams, scheduling too many teams will result in an unwieldy number of games, particularly when there are a limited number of playing surfaces (championship curling arenas usually only have four or five sheets).

A special type of group tournament is the Round-robin tournament, in which each player plays against every other player. Usually each competitor finishes with an equal number of matches, in which case rankings by total points and by average points are equivalent at the end of the tournament, though not necessarily while it is in progress.
The final incarnation with the introduction of the full round robin system. 2003 Campeonato Brasileiro Série A. The league featured 24 teams playing for the 1st time in the full round-robin system (called in Brazil "pontos corridos", i.e. running points), which is used in other major leagues. The formula was judged anti-Brazilian as it ...
