Learn the difference between directed and undirected graphs, and how they affect the properties and operations of graphs in computer engineering.

Learn what distinguishes directed and undirected graphical models, how they relate to each other, and what are their applications and examples.

To create a directed graph in Python for solving problems on LeetCode, you typically represent the graph using data structures such as adjacency lists.

Hi DGL team, I had a quick query re. directed and undirected graphs in DGL. In the example referenced above for OGBN-ARXIV, the graph is defined as a directed graph originally, but one needs to make ...

Introduction This paper presents a graph cut approach to the image segmentation task. Considering the image to be a directed graph with two nodes representing the source (object) and the sink ...

Introduction: Voxel hierarchy on dynamic brain graphs is produced by k-core percolation on functional dynamic amplitude correlation of resting-state fMRI. Methods: Directed graphs and their ...

Networks are graphs with weighted edges, where numerical values on edges specific quantities such as distance, time, or capacity. These can be either directed or undirected, and invaluable for ...

Trophic coherence and non-normality are both ways of describing the overall directionality of directed graphs or networks. Trophic coherence can be regarded as a measure of how neatly a graph can be ...
