Function Documentation

static bool tlp::AcyclicTest::acyclicTest ( const Graph ,
std::vector< edge > *  obstructionEdges = 0 
) [static, inherited]

Returns true if the graph is acyclic, false otherwise. If the graph is not acyclic, uses obstructionEdges variable to store all edges that create cycle.

static void tlp::ConnectedTest::computeConnectedComponents ( Graph graph,
std::vector< std::set< node > > &  components 
) [static, inherited]

Computes the sets of connected components and stores the result in the components vector.

static void tlp::AcyclicTest::makeAcyclic ( Graph graph,
std::vector< edge > &  reversed,
std::vector< tlp::SelfLoops > &  selfLoops 
) [static, inherited]

Makes the graph acyclic, by reversing edge direction (feedback arc set problem). If there is self loops, a new node is added with two edges that points to it.

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

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

static void tlp::ConnectedTest::makeConnected ( Graph graph,
std::vector< edge > &  addedEdges 
) [static, inherited]

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

static unsigned int tlp::ConnectedTest::numberOfConnectedComponents ( const Graph *const   graph  )  [static, inherited]

Returns the number of connected components in the graph.
