Polylogarithmic Inapproximability of the Radio Broadcast Problemhs of at most logarithmic radius, an .(log..) additive approximation algorithm is known, hence our lower bound is tight. To the best of our knowledge, this is the first tight additive polylogarithmic approximation result.

Topological Dynamics on the Interval,be satisfied. We give an exact algorithm for trees and show how this can be combined with a result of R?cke to give a solution that exceeds edge capacities by at most .(log.. log log.), where . is the number of nodes. On graphs of bounded treewidth, we show the problem is still NP-Hard, but we are a

Ergodic Theory and Dynamical Systems IIh agents must be motivated to report their true values for the figures as well as to report the true figures. Moreover, an approximation algorithm should be used for guaranteeing a reasonable solution for the underlying NP-complete problem. We present truthful mechanisms that guarantee a certain fra
