Abstract [en]

The uncapacitated network design problem is considered. We show that the feasible polytope of the continuous relaxation of this problem has the property that any path along the edges of the convex hull of its integer points is also a path along the edges of the polytope itself. This property may be of computational interest since it implies the possibility of solving the uncapacitated network design problem by a pivoting scheme. © 1992.
