An adjacency matrix is a way of representing a graph as a matrix of booleans (0's and 1's). A finite graph can be represented in the form of a square matrix on a computer, where the boolean value of the matrix indicates if there is a direct path between two vertices. ...
An edge list is a simple representation where each edge is stored as a pair of vertices. It is space-efficient for very sparse graphs but does not support efficient edge lookups.Compressed Adjacency MatrixFor large graphs with many missing edges, compressed representations of the adjacency matrix,...
