It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Webundirected graphs, it is considered connected if you can get from any vertex a to any other vertex b. (i.e. the graph is all in one cluster, there are not disjoint sets of nodes in your graph). For directed graphs, we introduce the idea of strongly and weakly connected. The definition of strongly connected is the same as the undirected graph ...

WebOct 17, 2024 · 1 Answer. First let me give another common way of computing the Laplacian of an undirected graph G = ( V, E) that generalizes more easily to the directed weighted graphs you are interested in. Suppose V = ( v 1, …, v n) and E = { 1, …, m } and fix an arbitrary orientation on the edges. Consider the vertex space R V with standard basis { e 1 ... WebAny shape that has 2 or more vertices/nodes connected together with a line/edge/path is called an undirected graph. Below is the example of an undirected graph: Undirected graph with 10 or 11 edges. Vertices are the result of two or more lines intersecting at a point. Edges or Links are the lines that intersect.
