A round robin is an arrangement of choosing all elements in a group equally in some rational order, usually from the top to the bottom of a list and then starting again at the top of the list and so on.

Round Robin Scheduling Program In Visual Basic
In computer operations, round robin is used in a scheduling algorithm that distributes work evenly among all available resources. This ensures that no single resource is overworked, which can lead to errors and other issues down the line.
In sports teams like those found in the NFL, NBA, MLB or NHL, a round robin is a method of scheduling where each participant plays against all other participants in the event. This is also referred to as a round robin tournament.
In gambling and sports betting, a round robin is used as a betting strategy. This means that instead of betting on one game or event, the bettors take stakes on multiple games or events. This is also referred to as parlay betting.
In the above code, we ask the user to enter the number of processes and arrival time and burst time for each process. We then calculate the waiting time and the turn around time using the round-robin algorithm.
Hi Oscar,
I found this during my searches for finding a "perfect" scheduler of round-robun tournament, and i have to say this is closely to perfection.
The only thing I can remark, is that system home-away is not so accurate, even in your example, Player 3 plays 2 times away (round 5 and 6) and Player 10 2 times (round 8 and 9), and exemples still there are, with Player 7...
Maybe a round robin tournament could not be perfect, regarding home-away matches ?
The system treats all threads with the same priority as equal. The system assigns time slices in a round-robin fashion to all threads with the highest priority. If none of these threads are ready to run, the system assigns time slices in a round-robin fashion to all threads with the next highest priority. If a higher-priority thread becomes available to run, the system ceases to execute the lower-priority thread (without allowing it to finish using its time slice) and assigns a full time slice to the higher-priority thread. For more information, see Context Switches.
Hi Ali, Thanks for the greate package.
I have got a problem with the collection when the input data was empty.
In an empty round roubin list the Next() method call would throw a NullReferenceException but I thinks it is better to throw more accurate exception to indicate that an empty list is not a normal state of round robin collection.
I have also created a pull request for the change.
But if you prefer that an empty round roubin collection does not need to be an invalid state of collection, in that case I can come up with the solution to deal with emty input data gracefully and not throwing exceptions.
Now when my app is running, if a machine goes down or fails somehow, I'd like to decrement the weight by 1, and if a machine goes down for a long time, it'd be taken off of our round robin, but before it reaches 0 and it comes back online, then we could reset it back to original value.
The Vanilla FreeRTOS scheduler implements time slicing meaning that if current highest ready priority contains multiple ready tasks, the scheduler will switch between those tasks periodically in a round robin fashion.
Abstract:Recently, there has been significant growth in the popularity of cloud computing systems. One of the main issues in building cloud computing systems is task scheduling. It plays a critical role in achieving high-level performance and outstanding throughput by having the greatest benefit from the resources. Therefore, enhancing task scheduling algorithms will enhance the QoS, thus leading to more sustainability of cloud computing systems. This paper introduces a novel technique called the dynamic round-robin heuristic algorithm (DRRHA) by utilizing the round-robin algorithm and tuning its time quantum in a dynamic manner based on the mean of the time quantum. Moreover, we applied the remaining burst time of the task as a factor to decide the continuity of executing the task during the current round. The experimental results obtained using the CloudSim Plus tool showed that the DRRHA significantly outperformed the competition in terms of the average waiting time, turnaround time, and response time compared with several studied algorithms, including IRRVQ, dynamic time slice round-robin, improved RR, and SRDQ algorithms.Keywords: cloud computing; task scheduling; round-robin; quantum time; CloudSim
A round robin tournament is a type of tournament in which each participant plays every other participant the same amount of times. If you have a large number of teams, you can choose to break your tournament up into different pools. Use our Number of Games in a Tournament calculator to determine the total number of games that will be played if every team plays every other team one time.
The round robin tournament is not as exciting, for the most part there is no championship final match. The matches in the later half of the tournament could have no impact on the final outcome of the tournament. One team may not be in the running for the championship, so therefore may not give as much effort. The are many instances where two teams will finish with the same record, when this happens you will need to refer to our Round Robin Tiebreaker Rules.
Nine types of tournaments or leagues are described in this book: single elimination, double elimination, multilevel, straight round robin, round robin double split, round robin triple split, round robin quadruple split, semi-round robins, and extended (such as ladder and pyramid tournaments). In the passages that follow, you will find the details on each kind of tournament or league, including individual strengths and weaknesses and suggestions for the best use for each tournament and league format.
Probably the best use for the single-elimination tournament is play-offs at the end of a season or following a longer tournament, such as a split round robin. You would then determine seeding for the single elimination by the standings at the conclusion of the previous playing period. Single-elimination tournaments are discussed in depth in chapter 2.
However, this tournament type is often overrated because of those strengths. It also has weaknesses, and there are alternatives. The major difficulties with the double elimination are that the second- and third-seeded entries play many games, particularly in the final rounds of the tournament, and it takes many rounds to complete. Also, this tournament type often uses available areas inefficiently. For example, if the tournament consists of nine entries and four locations are available, the double-elimination tournament takes seven rounds to complete. This is as many rounds as in a round robin double split (discussed later) but without the advantages a round robin tournament offers.
The round robin tournament and league schedules consist of all individuals or teams playing each entry an equal number of times. The round robin and round robin split tournaments all use fixed schedules; all entries know exactly who they play and what time they play them, which offers advantage to entries in preparing for the tournament and upcoming games. Seeding does not affect the outcome because the cumulative results of all games played determine final standings. When the number of entries is small and games are played quickly (as in table tennis, badminton, or volleyball), this type of format is effective for a one-day tournament. When there are more entries and the games take longer to complete (as in hockey, football, or basketball), then a round robin schedule is best suited for league play. In this case, one time through a round robin provides the league schedule, and, if time permits, you could provide a home and away schedule simply by going through the round robin schedule twice.
The round robin format is not suitable for all situations. Because all entries play each other, a round robin format is problematic when the number of entries is high. For example, a tournament with 32 entries would take 496 games to complete using a round robin. This compares with 62 games in a double elimination and 31 in single elimination. Also, when there is considerable discrepancy in the caliber of play, many games or matches will prove unsatisfactory to all involved in these noncontests. For more on the regular round robin tournament and the other round robin formats discussed in the following paragraphs, see chapter 5.
The largest number of schedules on the accompanying website is for round robins. To help you find the schedule you want, the files have been divided into five main folders: 3-8 entries and 9-12 and 13-16 entries, locations shared and locations different. Within those folders, the files are further subdivided by type of round robin and by league. The league schedules have a home location. The other round robin schedules could also be used for league schedules in which entries share locations. For example, a community soccer league of 10 teams might share two soccer fields.
