"WebFeb 3, 2024 · In an undirected graph, all edges are bi-directional. If the edges in the graph have weights (represent costs or distances), the graph is said to be a weighted graph. If the edges do not have weights, the graph is said to be unweighted. Graph can be presented as adjacency list or adjacency matrix. An adjacency list is an array of edges or nodes.

To find the shortest path from a vertex u to a vertex v on an unweighted graph (where "distance" is measured by number of edges), we can use a breadth-first search. A BFS results in a BFS tree; if two vertices u and v are connected by the BFS, then the BFS tree yields the shortest path by definition.

WebFeb 20, 2024 · The shortest path in an unweighted graph is the one with the fewest edges. You always reach a vertex from a given source using the fewest amount of edges when utilizing breadth-first. In unweighted graphs, any spanning tree is the Minimum Spanning Tree, and you can identify a spanning tree using either depth or breadth-first traversal.
