Breadth first search using adjacency matrix

WebJun 11, 2024 · Adjacency Matrix. Adjacency list is a list of lists. Where each list is a vertex and its corresponding edges therein. The advantage of a list over matrix is that list consumes less space. Matrix takes O(v²) space requirement. Queries are pros for matrix because finding one vertex to another takes O(1). This implementation will use … WebJul 17, 2024 · If you want to compute this from scratch, you'll be better off using graph-style algorithms instead of matrix terminology, specifically a breadth-first search or depth-first search. These can be implemented in terms of the adjacency matrix, although it will be less efficient than the built-in used in the graph object.
