We use a network simplex algorithm for assigning ranks. We also use =
this same algorithm for adjusting final x coordinates by creating an =
auxilary graph as described by Stephen North et al (A technique for =
directed graphs or something). The rank ordering is done using the =
tried but true approach of sweeping up and down the rows and assigning =
values to the nodes and sorting them (Sugiyama). We some modified =
barycenter method I think.

and yes I know about the description in the help. I'm mainly wondering =
if there's a name for it "in the literature"
