Lowest Common Ancestor(LCA)
Before embarking into the technicalities of the different algorithms for LCA, let us first agree on the terminology that we will be using throughout this article. Let there be a rooted tree T(E,V). A node x ∈ T is called an ancestor of a node y ∈ T if the path from the root of T to y goes through x. Also, a node v ∈ T is called to be a common ancestor of x and y if it is an ancestor of both x a...
متن کامل2 Least Common Ancestor
In particular, we are allowed to preprocess the texts in order to be able to answer the query faster. Our preprocessing choice was the use of a single suffix tree, in which all the suffixes of all the texts appear, each suffix ending with a distinct symbol that determines the text in which the suffix appears. In order to answer the query we reduced the problem to range-min queries, which in tur...
متن کاملLeast Common Ancestor Networks
Least Common Ancestor Networks (LCANs) are introduced and shown to be a class of networks that include fat-trees, baseline networks, SW-banyans and the router networks of the TRAC 1.1 and 2.0, and the CM-5. Some LCAN properties are stated and the permutation routing capabilities of an important subclass are analyzed. Simulation results for three permutation classes verify the accuracy of an ite...
متن کاملThe last common bilaterian ancestor.
Many regulatory genes appear to be utilized in at least superficially similar ways in the development of particular body parts in Drosophila and in chordates. These similarities have been widely interpreted as functional homologies, producing the conventional view of the last common protostome-deuterostome ancestor (PDA) as a complex organism that possessed some of the same body parts as modern...
متن کاملThe common ancestor process revisited.
We consider the Moran model in continuous time with two types, mutation, and selection. We concentrate on the ancestral line and its stationary type distribution. Building on work by Fearnhead (J. Appl. Probab. 39 (2002), 38-54) and Taylor (Electron. J. Probab. 12 (2007), 808-847), we characterise this distribution via the fixation probability of the offspring of all individuals of favourable t...
