*This method has a list, for every vertex, of every element adjacent to that vertex.*

Each of these methods has its own strengths and weaknesses.

Like with any data structure, you should pick your implementation based on the way(s) that you plan on querying the data, and the expected “shape” of the data.

Adjacency lists are the typical choice for “general purpose” use, though edge lists or adjacency matrices have their own strengths, which may match a specific use case.

Abstracting graph access is vital if your graph is going to span more than a single function call.

In particular, the edge:vertex ratio and the degree of the highest-degree vertices tend to be common metrics.

Edge lists are an extremely simple way to represent a graph. a list of edges, often just in the form of [source, destination] vertex pairs.Adjacency matrices perform strongly with edge lookups, with a constant-time lookup given a pair of vertex IDs.They tend to be slow for other operations — for example, listing everything adjacent to a vertex requires checking every single vertex in the graph.Graph theory is a branch of mathematics, first introduced in the 18th century, as a way to model a puzzle.Graphs are excellent at creating simplified, abstract models of problems.They also typically require more space than other models, especially with sparse graphs (graphs with “few” edges).An adjacency matrix needs to reference every vertex against every other vertex, giving O(|V(G)|) space needed.Unlike many traditional methods of structuring data, which focus on the This may look somewhat simple, but the terminology, classifications, and analytics of graphs can quickly get hairy.Let’s take a look deeper into graph theory and graph modeling.The body of graph theory allows mathematicians and computer scientists to apply many known principals, algorithms, and theories to their model. It is composed of two kinds of elements, vertices and edges (sometimes called nodes and links in computer science). Let each vertex represent a team, and let each edge represent a game between teams.Let’s look at using graph theory to quickly solve a problem. I want each of those teams to play exactly 3 games — is this possible? There is a principal, known sometimes as “the handshake lemma”, which states that a graph must have an dd degree).
