Topological.Make_stable
Provide the same features than Make
, except that the resulting topological ordering is stable according to vertices comparison: if two vertices v1
and v2
are topologically equal, v1
is presented first to the iterator if and only if G.V.compare v1 v2 <= 0
. In particular, the resulting order is not dependent on the provided hash function. This property is not guaranteed by the functor Make
. The counterpart is a less efficient implementation: worst time complexity is O(E*V*ln(V)) instead of O(E*V) (with E = number of edges and V = number of vertices.
