In a directed graph, an edge is typically represented as an ordered pair of vertices, such as (A, B), which means there is a directed edge from vertex A to vertex B.

Vertex-frequency analysis (VFA) is a useful technique in graph signal processing to extract the correspondence between frequencies and vertices. VFA can be calculated by the windowed graph Fourier ...

This project explores the minimum vertex cover problem in graph theory. A vertex cover is a set of vertices such that each edge in the graph has at least one endpoint in this set. Finding the smallest ...

This Java Spring Boot application finds the longest directed path in a directed acyclic graph (DAG) beginning at a given vertex. Graph theory, specifically topological sorting, is utilized in the ...

Graph cover problems form a critical area within discrete optimisation and theoretical computer science, addressing the challenge of selecting subsets of vertices (or edges) that satisfy ...

A Constant Factor Approximation for Directed Feedback Vertex Set in Graphs of Bounded Genus Citation: Sun, H. . (2023). A Constant Factor Approximation for Directed Feedback Vertex Set in Graphs of ...

Brain connectivity networks play a crucial role in understanding the organization and functioning of the human brain. In this regard, graph theoretical models may provide a powerful way for the ...

Hi Guys, I am just playing with dijkstra algorithm in C# and got it working good but now I want to modify it to get all the possible paths from the start and target nodes. Any advise?

From a numerical perspective, directed graphs lead to asymmetric matrices, which are far more difficult to handle than their symmetric counterparts. As a result, the key to many recent advances in ...
