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 ...
In general, a consensus algorithm can make progress using = + processors, despite the simultaneous failure of any processors: [13] in other words, the number of non-faulty processes must be strictly greater than the number of faulty processes. However, using reconfiguration, a protocol may be employed which survives any number of total failures ...
and: (,) = (,) (,)Taxa and are the paired taxa and is the newly created node. The branches joining and and and , and their lengths, (,) and (,) are part of the tree which is gradually being created; they neither affect nor are affected by later neighbor-joining steps.
It is a distributed algorithm that coordinates all the processes that participate in a distributed atomic transaction on whether to commit or abort (roll back) the transaction. This protocol (a specialised type of consensus protocol) achieves its goal even in many cases of temporary system failure (involving either process, network node ...
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]
For example, a solution to the Weak Byzantine General problem in a synchronous authenticated message passing model leads to a solution for Weak Interactive Consistency. [8] An interactive consistency algorithm can solve the consensus problem by having each process choose the majority value in its consensus vector as its consensus value. [9]

A different approach to this issue is followed in the ESPRESSO algorithm, developed by Brayton et al. at the University of California, Berkeley. [4] [3] It is a resource and performance efficient algorithm aimed at solving the heuristic hazard-free two-level logic minimization problem. [13]
