Re: [jgrapht-users] Implement composition of graphs

[J K. <j.k...@gm...>]

You need to be a bit more explicit as what you want/need. I have no idea
what you mean by "composition of binary relations as digraph". There is no
representation of "binary relations". Obviously, there are plenty of
different digraphs and algorithms available. Many algorithms can be easily
implemented using the building blocks that are already present in the
library.
