The edges indicate a two-way relationship, in … WebAn undirected graph is graph, i.e., a set of objects (called vertices or nodes) that are connected together, where all the edges are bidirectional. An undirected graph is sometimes called an undirected network. In contrast, a graph where the edges point in a direction is called a directed graph.

WebUndirected Graphs We define an undirected graph API and consider the adjacency-matrix and adjacency-lists representations. We introduce two classic algorithms for searching a graph—depth-first search and breadth-first search. We also consider the problem of computing connected components and conclude with related problems and applications. WebMar 29, 2024 · An undirected graph is a graph in which edges don't have orientation (no arrowhead). This means that an edge (u, v) is identical to edge (v, u). An example for this type of graph could be nodes representing cities and edges representing roads between cities.

WebDec 1, 2024 · A network has to be either directed or undirected. That said, you can work around that, a bit. Similar to the answer you found, you create a directed network, and pass in an argument that keeps track of whether the edge is directed or not. You can use this when you plot, or to subset your network:
