static bool isBiconnected (const Graph *graph)
 
static void makeBiconnected (Graph *graph, std::vector< edge > &addedEdges)
 

Detailed Description

Performs a test of biconnexity on the graph, and provides a function to make a graph biconnected. From Wikipedia: "A biconnected graph is connected and nonseparable, meaning that if any vertex were to be removed, the graph will remain connected.".

◆ isBiconnected()

static bool tlp::BiconnectedTest::isBiconnected ( const Graph graph)
static

Checks whether the graph is biconnected (i.e. removing one edge does not disconnect the graph, at least two must be removed).

Parameters
graphThe graph to check for biconnectivity.
Returns
bool True if the graph is biconnected, false otherwise.

◆ makeBiconnected()

static void tlp::BiconnectedTest::makeBiconnected ( Graph graph,
std::vector< edge > &  addedEdges 
)
static

Adds edges to make the graph biconnected.

If the graph is not biconnected, adds edges in order to make the graph biconnected. The new edges are added in addedEdges.

Parameters
graphThe graph to make biconnected.
addedEdgesThe edges that were added in the process.
Returns
void
