A simpler and better derandomization of an approximation algorithm for single source rent-or-buy
We present a very simple way of derandomizing the algorithm proposed by Gupta, Kumar and Roughgarden for Single Source Rent-or-Buy by using the method of conditional expectation. Using the improved analysis of Eisenbrand, Grandoni and Rothvoß, our derandomized algorithm has an approximation guarantee of 3.28.
