Hi, I was wondering from a lot of time, I can't get, if the contraction hierarchies is completely safe, just to know, that method alters the actual nodes? or it keeps all the graph nodes?

It should keep all nodes, the basic principle is to create "hierarchized" shortcuts to decrease search space during query.
