Fully Dynamic Algorithms for Bin Packing: Being (mostly) Myopic Helps
The problem of maintaining an approximate solution for one-dimensional bin packing when items may arrive and depart dynamically is studied. In accordance with various work on fully dynamic algorithms, and in contrast to prior work on bin packing, it is assumed that the packing may be arbitrarily rearranged to accommodate arriving and departing items. In this context our main result is a fully d...
متن کاملFully Dynamic Bin Packing Revisited
We consider the fully dynamic bin packing problem, where items arrive and depart in an online fashion. The goal is to minimize the number of used bins at every timestep while repacking of already packed items is allowed. Ivković and Lloyd [IL98] have developed an algorithm with asymptotic competitive ratio of 5/4 using O(log n) (amortized) shifting moves whenever an item is inserted or removed ...
متن کاملFully-Dynamic Bin Packing with Limited Repacking
We consider the bin packing problem in a fully-dynamic setting, where new items can arrive and old items may depart. The objective here is to obtain algorithms achieving low asymptotic competitive ratio while changing the packing sparingly between updates. We associate with each item i a movement cost ci ≥ 0. We wish to achieve good approximation guarantees while incurring a movement cost of β ...
متن کاملA Tight Approximation for Fully Dynamic Bin Packing without Bundling
We consider a variant of the classical Bin Packing Problem, called Fully Dynamic Bin Packing. In this variant, items of a size in (0,1] must be packed in bins of unit size. In each time step, an item either arrives or departs from the packing. An algorithm for this problem must maintain a feasible packing while only repacking a bounded number of items in each time step. We develop an algorithm ...
متن کاملParallel Approximation Algorithms for Bin Packing
We study the parallel complexity of polynomial heuristics for the bin packing problem. We show that some well-known (and simple) methods like first-fit-decreasing are P-complete, and it is hence very unlikely that they can be efficiently parallelized. On the other hand, we exhibit an optimal NC algorithm that achieves the same performance bound as does FFD. Finally, we discuss parallelization o...
