Hey *  Pengzhan Hao,

the graph files are (mostly) independent from the algorithm, they are just
used to avoid the costly reparsing of the OSM file everytime you restart
GraphHopper. The only difference is that CH creates some additional edges,
so called shortcuts.

The graph is organized as described here:
https://github.com/graphhopper/graphhopper/blob/master/docs/core/quickstart-
from-source.md#2-the-graph

Regards,
Peter.



Just focus on GH project , and interested in few questions:

It occurs to me that by using CHs algorithm ,several intermediate data
binary files appeared.

So what these files used for and how them organized in a data structure?
