We present the first learning-augmented data structure for implementing dictionaries with optimal consistency and robustness.

Time Fairness in Online Knapsack Problems

1 code implementation22 May 2023 Adam Lechowicz, Rik Sengupta, Bo Sun, Shahin Kamali, Mohammad Hajiesmaili

We propose a parameterized deterministic algorithm where the parameter precisely captures the Pareto-optimal trade-off between fairness (static pricing) and competitiveness (dynamic pricing).

Online Search With Best-Price and Query-Based Predictions

2 code implementations2 Dec 2021 Spyros Angelopoulos, Shahin Kamali, Dehou Zhang

In the standard definition of the problem, for each revealed price, the player must decide irrevocably whether to accept or reject it, without knowledge of future prices (other than an upper and a lower bound on their extreme values), and the objective is to minimize the competitive ratio, namely the worst-case ratio between the maximum price in the sequence and the one selected by the player.
