WebGraph Concepts. The heart of the Boost Graph Library (BGL) is the interface, or concepts (in the parlance of generic programming), that define how a graph can be examined and manipulated in a data-structure neutral fashion. In fact, the BGL interface need not even be implemented using a data-structure, as for some problems it is easier or more ...
