Approximating the Best-Fit Tree Under , , Normsting..We also consider the problem of finding an ultrametric . that minimizes ..elative: the sum of the factors by which each input distance is stretched. For the latter problem, we give a factor .(log..) approximation.

F. Kraus,O. Minkowski,A. Schittenhelm solving a standard SDP relaxation of MAX CUT and then rounds the optimal solution obtained using a random hyperplane. In some cases, the optimal solution of the SDP relaxation happens to lie in a low dimensional space. Can an improved performance ratio be obtained for such instances? We show that t
