Description (last modified by )
A simpler (but in fact equivalent) form of the Network Flow Problems when we have no upper limit on the arcs. We can also assume that the lower limit is 0 everywhere.
In this case Network Simplex algorithms becomes much easier:
- A basis is just a tree, and it's trivial to obtaine both the primal and the dual solutions from it.
- A starting dual feasible solution is just a feasible potential w.r.t. the cost, so it can be computed by a shortest path algorithm.
