Our algorithms admit order-preserving metrics and thus significantly generalize and improve the allowed mutability of the metric in comparison to previous algorithms, which only allow scenario-dependent inflation factors.

,Zentralnervensystem und perniziöse Anämie, sub-class of Second-Order Cone Programming. We show how to extend the multiplicative weights update method to derive approximation schemes for the above packing and covering problems. When the sets . are simple, such as ellipsoids or boxes, this yields substantial improvements in the running time over general convex programming solvers.

Finally, we discuss an elegant relation with an . minimum spanning tree problem.
