leaf node


  • WordNet 3.6
    • n leaf node (botany) the small swelling that is the part of a plant stem from which one or more leaves emerge
    • ***


In literature:

At each walnut node or leaf we have as many as seven buds, all of which are capable of producing growth.

The leaf-nodes are swollen into small, warty prominences, which are especially resinous.

In news:

With current growth stages ranging from Feekes 6 to 8, wheat growers in the Midwest need to be on the look out for the presence of nodes and the emergence of flag leaf.
Make pruning cuts on an angle just above an upward/outward-facing eye (a leaf node or a bump on the branch).

In science:

The labels of internal (non-leaf ) nodes are referred to as tags, whose purpose is to describe those data elements.
Using Tree Automata and Regular Expressions to Manipulate Hierarchically Structured Data
However it is easy to see that xr,i is independent of α if the node (r, i) is a leaf of the tree.

The node v of the diagram Σ is called a leaf of the diagram Σ, if v belongs to exactly one edge of Σ.
On simple ideal hyperbolic Coxeter polytopes
Furthermore, since ΣW is a parabolic diagram of order n > 5, one of the nodes u and v of the double edge uv is a leaf.

In Random-Turn AND-OR, the player who wins the coin toss sets the bit at a leaf node.
Random-Turn Hex and other selection games
We respectively call nodes v2 and v1 right and left children of v . A node without children is called a leaf.
An example of generalized Schur operators involving planar binary trees
These equations can be easily solved, for a given initial satisfying assignment σ, noting that the messages from the leaf variable nodes i satisfy the boundary condition ~ni→a (σi ) = ~o(σi ), where we define [~o(σ)]τ = I(σ 6= τ ).

Example 2.11 Let K = Kk (∃path ) be the set of all trees in ∆Mk such that all the nodes along at least one path from the root to a leaf are labeled 1n (for appropriate values of n).
Algebraic characterization of logically defined tree languages
Then (t, λ) satisfies QK x · hϕn in if and only if there exists a root-to-leaf path such that, for every node v ∈ NV(t) along this path, (t, λv ) |= ϕn (x) (where n is the rank of v).
Algebraic characterization of logically defined tree languages
If x ∈ Z but y 6∈ Z, we let ϕ′ = true or false depending whether the node of U where x occurs in an ancestor of the (k1 + 1)-st variable leaf.
Algebraic characterization of logically defined tree languages
The ob ject of our study was to find what happens when we constrain to connected graphs only. A simple argument indicated that correlations would appear: a neighbor of a node with degree one (leaf ) must have its degree greater than 1; otherwise, they would form a separate connected component.
Correlations in connected random graphs
Proposition 3.1: Given BL and Fmax, there exists an optimal solution of BLOCK-ALL that can be represented as a pruned subtree of LCP-tree(BL) with: the same root, up to Fmax leaves, and non-leaf nodes having exactly two children.
Optimal Filtering of Malicious IP Sources
The same argument recursively applies to descendant nodes, until either we reach a leaf node, or we have only one filter available.
Optimal Filtering of Malicious IP Sources
We note that since any LCP-tree is also a binary tree, there are at most log(N ) predecessors of any leaf node, thus the above procedure requires O(log(N )Fmax ) operations.
Optimal Filtering of Malicious IP Sources
Suppose that at each inner node (i.e., node that is not a leaf ) a total ordering of its children is given.
