[jgrapht-users] Calculating union of graphs (AsGraphUnion at al)

[Victor P. <po...@na...>]

I need to calculate union of graphs.

AsGraphUnion does the task, but when I add say 10 graphs, it creates a
multi-level structure, what 1. takes memory and CPU; 2. may lead to
unexpected errors when I modify the graphs in the system.

How to do a copy of AsGraphUnion into a regular DefaultDirectedGraph?
