Algorithms dealing with various connectivity aspects of a graph. A graph is connected when there is a path between every pair of vertices. In a connected graph, there are no unreachable vertices. A graph that is not connected is disconnected. A connected component is a maximal connected subgraph of $G$. Each vertex belongs to exactly one connected component, as does each edge.

A directed graph is called weakly connected if replacing all of its directed edges with undirected edges produces a connected (undirected) graph. It is strongly connected if it contains a directed path from $u$ to $v$ and a directed path from $v$ to $u$ for every pair of vertices $u$, $v$. The strong components are the maximal strongly connected subgraphs.
