Decision-Theoretic Approaches for Improved Learning-Augmented Algorithms

Spyros Angelopoulos, Christoph Dürr, Georgii Melidi

We initiate the systematic study of decision-theoretic metrics in the design and analysis of algorithms with machine-learned predictions. We introduce approaches based on both dete…

Scenario-Based Robust Optimization of Tree Structures

Spyros Angelopoulos, Christoph Dürr, Alex Elenter +1

We initiate the study of tree structures in the context of scenario-based robust optimization. Specifically, we study Binary Search Trees (BSTs) and Huffman coding, two fundamental…

Contract Scheduling with Distributional and Multiple Advice

Spyros Angelopoulos, Marcin Bienkowski, Christoph Dürr +1

Contract scheduling is a widely studied framework for designing real-time systems with interruptible capabilities. Previous work has showed that a prediction on the interruption ti…
