[gecode-users] What is an 'oriented intersection-graph'?

[Conijn, B.J.]

Hi,

I was wondering what an oriented intersection-graph is? This term is mentioned in the documentation for Gecode::Int::Sorted::computesccs, but it is unclear how the orientations of the edges are defined. I suspect that computesccs does not compute the sccs of the oriented intersection-graph, which causes the bug in the sorted constraint.

Kind regards,

Bauke
