Online bin covering: Expectations vs. guarantees

Abstract: Bin covering is a dual version of classic bin packing. Thus, the goal is to cover as many bins as possible, where covering a bin means packing items of total size at least one in the bin.For online bin covering, competitive analysis fails to distinguish between most algorithms of interest; all "reasonable" algorithms have a competitive ratio of

“…Using ideas of Kenyon [11], it follows that AAPR(DNF) ≥ RR(DNF). We show that RR(DNF) ≤ AAPR(DNF) ≤ 2 /3, which improves a result by Christ et al [3] who proved that RR(DNF) ≤ 4 /5. To the best of our knowledge the bound by Christ et al is the only non-trivial result about the random-order ratio of DNF in the literature.…”

“…The asymptotic random-order ratio for bin covering and bin packing has been introduced in [3] and [11], respectively. All definitions above can also be adapted to the bin packing problem; we only have to replace inf and lim inf by sup and lim sup, respectively.…”

“…Random-order analysis has also been applied to other problems, e.g., knapsack [7], bipartite matching [43,35], scheduling [60,42], bin covering [30,41], and facility location [57]. However, the analysis is often rather challenging, and in [50], a simplified version of the random-order ratio is used for bin packing.…”
