A chart is a mathematical construct that consists of a group of vertices, also known as 'nodes,' and a group of edges that link pairs of vertices. Graphs are classified as either undirected or directed, with directed edges indicating the starting vertex from which they originate and the destination vertex to which they extend (whether it be another vertex or the same).

Setting up NEO4J graph database on your current Amazon EC2 instance

Currently, I have an adjacency list prepared for constructing a graph with 50,000 nodes and 100 million edges. My plan is to store this data in a graph database, specifically NEO4J. I am looking for guidance on how to download and install NEO4J for free ...

Enumerate every "distinct route" leading to a given node

I have a representation of a process through something that closely resembles a Directed Acyclic Graph (DAG). This graph is depicted using an adjacency table, but it's not your typical adjacency table as there are some key differences: Each entry in ...
