title = "Polylogarithmic inapproximability of the radio broadcast problem (Extended abstract)",

abstract = "We prove that there exists a universal constant c > 0 such that the Radio Broadcast problem admits no additive c · log2 n-approximation, unless NP ⊆ BPTIME(nO(log log n)). For graphs of at most logarithmic radius, an O(log2 n) 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.",
