[Boost-users] stopping dijkstra_shortest_path after target achieved

Dear ALL, Its probably a easy/dummy question, but as i`m new with template programming and i`ve seen no discussion about this in the mailing list... Is there an easy/already implemented way to stop the computation of the dijkstra_shortest_path algorithm when some target vertex is marked as black?? The problem is: i have a _huge_ graph and need to calculate the shortest distance between two points, but in 90% of all use cases the these points will be very close of each other, so doesn't make sense for me to keep the calculation until all shortest paths are found.. Best regards, Celso.
