[jgrapht-users] Implement composition of graphs

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

I need composition of digraphs (I mean composition of binary relations
represented as digraphs.) in my project. It seems that JGraphT is
missing this operation.

Is it really missing?

If it is missing I want to implement it.

I remind that composition is defined by the formula

x(R*S)z <=> exists y: (xSy and yRz)
