论文摘要
垃圾箱包装问题(BPP)是物流中的范式组合优化问题。量子和杂种量子古典算法有望在获得优化问题的近似解决方案方面表现出比其经典同行的优势。我们最近提出了一种杂种方法,用于一维BPP,其中采用量子退火子例程来对单个容器进行采样可行的溶液。从这个减少的搜索空间中,经典优化子例程可以找到解决问题的解决方案。为了进一步评估我们的子例程,在本文中,我们将程序的性能与其他经典方法进行了比较。具体来说,我们测试了随机抽样和基于随机的启发式的启发式。我们采用包括18个实例的基准测试标准,我们表明量子方法缺乏减慢经典算法的停滞行为。基于这一点,我们得出结论,可以与随机步行共同采用量子策略,以更少的迭代次数获得可行解决方案的完整样本。这项工作改善了我们对利用稀缺量子资源来改善有效经典策略的结果的直觉。
The Bin Packing Problem (BPP) stands out as a paradigmatic combinatorial optimization problem in logistics. Quantum and hybrid quantum-classical algorithms are expected to show an advantage over their classical counterparts in obtaining approximate solutions for optimization problems. We have recently proposed a hybrid approach to the one dimensional BPP in which a quantum annealing subroutine is employed to sample feasible solutions for single containers. From this reduced search space, a classical optimization subroutine can find the solution to the problem. With the aim of going a step further in the evaluation of our subroutine, in this paper we compare the performance of our procedure with other classical approaches. Concretely we test a random sampling and a random-walk-based heuristic. Employing a benchmark comprising 18 instances, we show that the quantum approach lacks the stagnation behaviour that slows down the classical algorithms. Based on this, we conclude that the quantum strategy can be employed jointly with the random walk to obtain a full sample of feasible solutions in fewer iterations. This work improves our intuition about the benefits of employing the scarce quantum resources to improve the results of a diminishingly efficient classical strategy.
