## Member Typedef Documentation

typedef CAP CapacityMap

The type of the map that stores the arc capacities. It must meet the ReadMap concept.

typedef GR::ArcMap<Value> FlowMap

The type of the map that stores the flow values. It must meet the ReadWriteMap concept.

typedef lemon::Elevator<GR, GR::Node> Elevator

The elevator type used by Preflow algorithm.

typedef lemon::Tolerance<Value> Tolerance

The tolerance used by the algorithm to handle inexact computation.
