Sentence examples for tree vertex from inspiring English sources

This selected vertex is not yet in the tree and is connected with any tree vertex with an edge having the largest weight.

The condition that each edge in N has a tree vertex as an endpoint and that each tree vertex has at least one tree vertex as a child, ensures that the set of leaves of the resulting tree is the same as that of the network.

In the Abstract this term is used in the common biological sense as a set of leaves-species descending from a tree vertex.

This approach reduces the complexity of the search for close (within distance 1) neighbors of a given tree vertex from O nS) to O(n).

Therefore, this parameter is more useful in sparser graphs, where not too many graph vertices are joined into a tree vertex.

Another component of this definition is that for any edge in the phylogenetic network, at least one of its endpoints (either the head or tail) is a tree vertex.

Also, when a gene lineage reaches a species-tree vertex, it always (i.e., deterministically) bifurcates and the two so contained gene lineages continue to evolve below the species-tree vertex, one in each of its two outgoing species-tree edges.

Whenever an event creates a new gene-tree vertex the time of the event is associated with the new vertex.

A pseudogene lineage otherwise behaves as a gene lineage, it may duplicate or become lost during the evolution, and it deterministically bifurcates when it reaches a species-tree vertex.

We call (v_{i}) the root of the tree if vertex i of the tree is not a terminal vertex of any arcs and each of the remaining vertices is a terminal vertex of one arc.

Another representation of the free monoid on n generators is as an infinite tree, every vertex of which has n descendants, one for each letter of the alphabet, with each edge labeled by the corresponding letter.
