A property graph has vertices that can contain detailed information about a subject, and edges that denote the relationship between the vertices. The vertices and edges can have attributes, called properties, with which they are associated. In this example, a set of colleagues and their ...

Mader proved that for k≥1 and n≥2k, every n-vertex graph with no (k+1)-connected subgraphs has at most (1+12)(n−k) edges. He also conjectured that for n large with respect to k, every such graph has at most 32(k−13)(n−k) edges. Yuster improved Mader’s upper bo...

suppose the nodes in a graph represent people and the edges between nodes represent an e-mail communication. You might be interested in the shortest number of hops between two people, where you’re implicitly assuming that each hop has a weight of 1. This is similar to the “six degrees ...
A property graph model makes modeling easier and more intuitive because it supports data relationships natively (no reification is involved). Property Graph Databases Property graph databases represent data as nodes (or entities), edges (the relationships between those entities), and properties (any ad...
This project accepts excel files as input which contains the description of a Knowledge Graph (Vertexes and Edges) and convert it into an in-memory Graph Store. This project implements APIs to search/filter/get nodes and relations from the in-memory Know
Find the root of the tree, which is the vertex with no incoming edges. If no node exists, then return . If more than one node exists, then the graph is not connected, and we should return as well. Perform a DFS to check that each node has exactly one parent. If not, return . ...
In this section, we’ll present a general formula to calculate the maximum number of edges that a directed graph can contain. Let’s assume an undirected graph with vertices. Further, we’re also assuming that the graph has a maximum number of edges. In such a case, from the starting ve...
Monitoring the edges of a graph using distances with given girth 2024, Journal of Computer and System Sciences Citation Excerpt : McCuaig and Shepherd [18] obtained the following classical result on the domination number of a graph with minimum degree at least 2. [7] Let G be a graph. G...
