[Lemon-user] EdgeLookup for SmartGraph

[Kovács Péter]

Hi,

In an undirected graph each edge is represented by two oppositely 
directed arcs. Therefore you can use ArcLookup tools (ArcLookUp, 
AllArcLookUp, DynArcLookUp) even if you are looking for an edge. For 
obtaining an {u,v} edge, just find an (u,v) or (v,u) arc, which converts 
to the corresponding edge.

Regards,
Peter
