摘要:

优先队列是计算机科学中最基础且最广泛使用的数据结构之一。其主要目标是高效支持插入带有指定优先级的新元素,以及提取最高优先级的元素。在本研究中,我们探讨了在学习增强框架下优先队列的设计,在该框架中,算法使用可能不准确的预测来增强其最坏情况性能。我们考察了涵盖不同用例的三种预测模型,并展示了如何利用这些预测来提升优先队列操作的性能。此外,我们证明了所提解决方案的最优性,并讨论了一些可能的应用场景。

英文摘要:

Priority queues are one of the most fundamental and widely used data structures in computer science. Their primary objective is to efficiently support the insertion of new elements with assigned priorities and the extraction of the highest priority element. In this study, we investigate the design of priority queues within the learning-augmented framework, where algorithms use potentially inaccurate predictions to enhance their worst-case performance. We examine three prediction models spanning different use cases, and show how the predictions can be leveraged to enhance the performance of priority queue operations. Moreover, we demonstrate the optimality of our solution and discuss some possible applications.
