WebMar 28, 2024 · If an undirected graph is connected, it must contain at least one path that visits each node at least once. You could construct an initial matrix where the second off-diagonal (adj(1, 2), adj(2, 3), ..., adj(n-1, n)) is always nonzero, and fill in the rest of the matrix randomly with E-n other edges. WebApr 10, 2024 · An undirected connected graph is a graph in which all vertices are connected to each other via edges. In such a graph, there exists a path between any two vertices. If we start from any vertex and traverse through the edges, we can reach all other vertices in the graph.
