WebDec 16, 2024 · The construction of the polynomial basis is based on a greedy, adaptive, sensitivity-related method. The sequential expansion of the experimental design employs different optimality criteria, with ... Webized greedy algorithm that achieves a 5:83 approximation and runs in O(nlogn) time, i.e., at least a factor nfaster than other state-of-the-art algorithms. The robustness of our approach allows us to further transfer it to a stochastic version of the problem. There, we obtain a 9-approximation to the best adaptive policy, which
Webachieves a (1 1=e)-approximation of the non-adaptive optimal solution, so its performance is always at least a (1 1=e) fraction of the performance of the non-adaptive greedy al … WebThey present a simple randomized greedy algorithm that achieves a 5.83 approximation. They also study the stochastic version of this problem. ... Given these previous works, combining these two steps seems straightforward. Furthermore, the extension to the adaptive case is somewhat straightforward given the result of [25]. b. The authors do not ...
