A fast … WebCHs are an extreme case of the hierarchies in highway-node routing (HNR) [3,2] – every node deﬁnes its own level of the hierarchy. CHs are nevertheless a new approach in the sense that the node ordering and hierarchy construction algorithms used in [3,2] are only eﬃcient for a small number of geometrically shrinking levels. bin ich charmant
