摘要:

本文针对在线背包问题引入了一族学习增强算法,通过简单组合可信的学习增强算法与最坏情况算法,实现了近乎帕累托最优的一致性-鲁棒性权衡。我们的方法依赖于简洁实用的预测——即单个值或区间,用于估计离线解中任意物品的最小值。此外,我们提出了一种新颖的分数到整数转换过程,为在线算法设计提供了新的见解。

英文摘要:

This paper introduces a family of learning-augmented algorithms for online knapsack problems that achieve near Pareto-optimal consistency-robustness trade-offs through a simple combination of trusted learning-augmented and worst-case algorithms. Our approach relies on succinct, practical predictions -- single values or intervals estimating the minimum value of any item in an offline solution. Additionally, we propose a novel fractional-to-integral conversion procedure, offering new insights for online algorithm design.
