Tree (graph theory) - Wikipedia

A directed tree, oriented tree, polytree, or singly connected network is a directed acyclic graph (DAG) whose underlying undirected graph is a tree. A ...

Polytree - Wikipedia

In mathematics, and more specifically in graph theory, a polytree is a directed acyclic graph whose underlying undirected graph is a tree.

directed tree - DSPLAB - Univerza v Mariboru

A tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph.

Are Trees Directed or Undirected Graphs? - Stack Overflow

Trees are connected acyclic graphs. that means you should be able to traverse from any node u to any node v.

Discrete Mathematics Introduction of Trees - Javatpoint

Directed Trees: ... The node which has outdegree 0 is called an external node or a terminal node or a leaf. The nodes which have outdegree greater than or equal ...

What is the equivalent of a tree for directed graphs?

A tree is a connected digraph that has no circuit—neither a directed circuit nor a semicircuit. A tree of n vertices contains n − 1 directed ...

How do we define a tree in a directed graph?

The problem is to find a minimum cost tree in G rooted into r that contains all the required vertices and any subset of the Steiner vertices.

Determining Whether a Directed or Undirected Graph Is a Tree

In this tutorial, we'll explain how to check if a given graph forms a tree. We'll explain the concept of trees, and what it means for a graph to form a tree.

Directed tree-width - Princeton University

Abstract. We generalize the concept of tree-width to directed graphs and prove that every directed graph with no "haven" of large order has small tree-width.

Force-Directed Tree - amCharts

Force Directed Tree is a special kind of chart used to display of multi-item data related in hierarchical, linear or mixed way, as a series of linked bubbles.

Directed Tree-Width - ScienceDirect.com

We generalize the concept of tree-width to directed graphs and prove that every directed graph with no ``haven'' of large order has small tree-width.

What is the difference between a rooted tree and an acyclic directed ...

A rooted tree—also known as an arborescence—has the two “tree” properties: 1. There is exactly zero or one path between any two nodes ...

Directed Steiner tree packing and directed tree connectivity - 2023

In this paper, we completely determine the complexity for both and on general digraphs, symmetric digraphs, and Eulerian digraphs.

Estimating a directed tree for extremes - Oxford Academic

The algorithm estimates bivariate scores and returns a root-directed spanning tree. It performs extremely well on benchmark data and on new data. We prove that ...

[2009.13184] The canonical directed tree decomposition and its ...

In this paper, we provide the canonical tree decomposition theorem for digraphs. More precisely, we construct directed tree-decompositions of digraphs.
