Fig. 1From: Heuristic algorithms for best match graph editingConstruction of the LRT for a BMG \((\vec {G},\sigma )\) using the BUILD algorithm. Each recursion step (pink boxes) corresponds to a vertex of the resulting tree (trivial steps on single vertices are omitted in the drawing). The algorithm recurses on the connected components (gray dashed boxes) of the Aho graphs and the corresponding subsets of triplesBack to article page
