Bully algorithm. In distributed computing, the bully algorithm is a method for dynamically electing a coordinator or leader from a group of distributed computer processes. The process with the highest process ID number from amongst the non-failed processes is selected as the coordinator.
The two part algorithm can be described as follows: Initially each process in the ring is marked as non-participant. A process that notices a lack of leader starts an election. It creates an election message containing its UID. It then sends this message clockwise to its neighbour. Every time a process sends or forwards an election message, the ...
Comparison of voting rules. A major branch of social choice theory is devoted to the comparison of electoral systems, otherwise known as social choice functions. Viewed from the perspective of political science, electoral systems are rules for conducting elections and determining winners from the ballots cast.
Paxos (computer science) Paxos is a family of protocols for solving consensus in a network of unreliable or fallible processors. Consensus is the process of agreeing on one result among a group of participants. This problem becomes difficult when the participants or their communications may experience failures.
Instant-runoff voting. Instant-runoff voting (IRV) is a winner-takes-all multi-round elimination voting system [needs context] that uses ranked voting to simulate a series of runoff elections, where the last-place finisher according to a plurality vote is eliminated in each round. Its purpose is to elect the candidate in single-member districts ...
Random ballot. A random ballot or random dictatorship is a randomized electoral system where the election is decided on the basis of a single randomly-selected ballot. [ 1 ][ 2 ] A closely-related variant is called random serial (or sequential) dictatorship, which repeats the procedure and draws another ballot if multiple candidates are tied on ...
After weeks of what one official called bullying and intimidation, tensions are running high at the Shasta County elections office. 'Bullying': With recall at hand, county elections workers say ...
The Boyer–Moore majority vote algorithm is an algorithm for finding the majority of a sequence of elements using linear time and a constant number of words of memory. It is named after Robert S. Boyer and J Strother Moore, who published it in 1981, [1] and is a prototypical example of a streaming algorithm. In its simplest form, the algorithm ...
