  2. Paxos (computer science) - Wikipedia

    en.wikipedia.org/wiki/Paxos_(computer_science)

    Generalized consensus explores the relationship between the operations of the replicated state machine and the consensus protocol that implements it. [16] The main discovery involves optimizations of Paxos when conflicting proposals could be applied in any order. i.e., when the proposed operations are commutative operations for the state ...

  3. Random sample consensus - Wikipedia

    en.wikipedia.org/wiki/Random_sample_consensus

    A simple example is fitting a line in two dimensions to a set of observations. Assuming that this set contains both inliers, i.e., points which approximately can be fitted to a line, and outliers, points which cannot be fitted to this line, a simple least squares method for line fitting will generally produce a line with a bad fit to the data including inliers and outliers.

  4. Conflict-free replicated data type - Wikipedia

    en.wikipedia.org/wiki/Conflict-free_replicated...

    An algorithm (itself part of the data type) automatically resolves any inconsistencies that might occur. Although replicas may have different state at any particular point in time, they are guaranteed to eventually converge. The CRDT concept was formally defined in 2011 by Marc Shapiro, Nuno Preguiça, Carlos Baquero and Marek Zawirski. [9]

  5. Consensus clustering - Wikipedia

    en.wikipedia.org/wiki/Consensus_clustering

    Consensus clustering is a method of aggregating (potentially conflicting) results from multiple clustering algorithms.Also called cluster ensembles [1] or aggregation of clustering (or partitions), it refers to the situation in which a number of different (input) clusterings have been obtained for a particular dataset and it is desired to find a single (consensus) clustering which is a better ...

  6. Consensus (computer science) - Wikipedia

    en.wikipedia.org/wiki/Consensus_(computer_science)

    An example of a polynomial time binary consensus protocol that tolerates Byzantine failures is the Phase King algorithm by Garay and Berman. [14] The algorithm solves consensus in a synchronous message passing model with n processes and up to f failures, provided n > 4f. In the phase king algorithm, there are f + 1 phases, with 2 rounds per ...

  7. De novo sequence assemblers - Wikipedia

    en.wikipedia.org/wiki/De_novo_sequence_assemblers

    These algorithms typically do not work well for larger read sets, as they do not easily reach a global optimum in the assembly, and do not perform well on read sets that contain repeat regions. [1] Early de novo sequence assemblers, such as SEQAID [ 2 ] (1984) and CAP [ 3 ] (1992), used greedy algorithms, such as overlap-layout-consensus (OLC ...

  8. Raft (algorithm) - Wikipedia

    en.wikipedia.org/wiki/Raft_(algorithm)

    Raft is a consensus algorithm designed as an alternative to the Paxos family of algorithms. It was meant to be more understandable than Paxos by means of separation of logic, but it is also formally proven safe and offers some additional features. [1]

  9. List of unsolved problems in computer science - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    The optimal algorithm to compute MSTs is known, but it relies on decision trees, so its complexity is unknown. Gilbert–Pollak conjecture : Is the Steiner ratio of the Euclidean plane equal to 2 / 3 {\displaystyle 2/{\sqrt {3}}} ?
