The online bin covering problem is: given an input sequence of items find a placement of the items in the maximum number of bins such that the sum of the items’ sizes in each bin is at least 1. Boyar et al. [3] present a strategy that with 𝑂(loglog𝑛) bits of advice, where n is the length of the input sequence, achieves a competitive ratio of 8/15≈0.5333…. We show that with a strengthened analysis and some minor improvements, the same strategy achieves the significantly improved competitive ratio of 135/242≈0.5578…, still using 𝑂(loglog𝑛) bits of advice.
