Functions

template<typename T >
node ogdf::steiner_tree::buildHeaviestEdgeInComponentTree (const EdgeWeightedGraphCopy< T > &inputTree, NodeArray< node > &externalNodes, NodeArray< edge > &treeEdge, Graph &outputTree)
 Given an edge-weighted tree, builds an auxiliary arborescence where each arc of the input tree is a node in the arborescence. More...
 
template<typename T >
void ogdf::steiner_tree::contractTripleInSteinerTree (const Triple< T > &t, EdgeWeightedGraphCopy< T > &st, edge e0, edge e1, edge e2)
 
template<typename T >
void ogdf::steiner_tree::contractTripleInSteinerTree (const Triple< T > &t, EdgeWeightedGraphCopy< T > &st, edge save0, edge save1, edge save2, edge &ne0, edge &ne1)
 Updates the Steiner tree by deleting save edges, removing all direct connections between the terminals of the contracted triple and connecting them through 0-cost edges. More...
 
template<typename T >
ogdf::steiner_tree::obtainFinalSteinerTree (const EdgeWeightedGraph< T > &G, const NodeArray< bool > &isTerminal, const NodeArray< bool > &isOriginalTerminal, EdgeWeightedGraphCopy< T > *&finalSteinerTree)
