Graph algorithms provide one of the most potent approaches to analysing connected data. They describe steps to be taken to process a graph to discover its general or specific quantities. In this talk we will introduce you to the Neo4j Graph Algorithms library, giving a brief overview of the different types of algorithms available, and where you might use them. We will also show you how to get set up with the Graph Algorithms library, as well as introducing you to NEuler, the Cypher-free graph algorithms playground.
