Research Type Theoretical First, we design deterministic and randomized online rounding algorithms for the problem in the unrelated machine setting, with O log m log log m and O log log m log log log m -competitive ratios. They respectively improve upon the previous ratios of O(log m) and O(log3 log m), and match the lower bounds given by Lattanzi et al. Second, we extend their prediction scheme from the identical machine restricted assignment setting to the unrelated machine setting. With the knowledge of two vectors over machines, a dual vector and a weight vector, we can construct a good fractional assignment online, that can be passed to an online rounding algorithm. Finally, we consider the learning model introduced by Lavastida et al. (2020), and show that under the model, the two vectors can be learned efficiently with a few samples of instances.
