Near-Optimal Consistency-Robustness Trade-Offs for Learning-Augmented Online Knapsack Problems

This paper introduces a family of learningaugmented algorithms for online knapsack problems that achieve near Pareto-optimal consistencyrobustness 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.
