Die chronischen Albuminurien im Kindesalter,y Kato, Imai, and Asano (ISAAC’02) have given a factor 2 approximation algorithm, however their correctness proof is incomplete. In this note, we propose a rounding 2-approximation algorithm based on a LP-formulation of the minimum Manhattan network problem.

On trees, we obtain an improved guarantee of .(log (.)). There is a natural Ω (log .) hardness of approximation for the requirement cut problem.

Approximation Schemes for Node-Weighted Geometric Steiner Tree Problemso find approximation schemes for geometric optimization problems that have a complicated topology. Furthermore the techniques we use provide a more general framework which can be applied to geometric optimization problems with more complex objective functions.
