Parallel 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...
متن کاملLinear time-approximation algorithms for bin packing
Simchi-Levi (Naval Res. Logist. 41 (1994) 579–585) proved that the famous bin packing algorithms FF and BF have an absolute worst-case ratio of no more than 4 , and FFD and BFD have an absolute worst-case ratio of 3 2 , respectively. These algorithms run in time O(n log n). In this paper, we provide a linear time constant space (number of bins kept during the execution of the algorithm is const...
متن کاملComparing online algorithms for bin packing problems
The relative worst-order ratio is a measure of the quality of online algorithms. In contrast to the competitive ratio, this measure compares two online algorithms directly instead of using an intermediate comparison with an optimal offline algorithm. In this paper, we apply the relative worst-order ratio to online algorithms for several common variants of the bin packing problem. We mainly cons...
متن کاملFrame Communication Module for Bin-Packing Algorithms
-Embedded real-time systems must satisfy not only logical functional requirements, but also para-functional properties such as timeliness, Quality of Service (QoS) and reliability. The proposed scheme describes an automated schedulability analysis, and generates glue code to integrate the final runtime executable for the system. Its extensive glue code generation capabilities include the abilit...
متن کاملBranch-and-price algorithms for the dual bin packing and maximum cardinality bin packing problem
There appear to be two versions of the Dual Bin Packing problem in the literature. In addition, one of the versions has a counterpart in the cutting stock literature, known as the Skiving Stock Problem. This paper outlines branch-andprice algorithms for both. We introduce combinatorial upper bounds and well-performing heuristics from the literature in the branch-and-price framework. Extensive c...
