Contract scheduling with predictions

S Angelopoulos, S Kamali - Journal of Artificial Intelligence Research, 2023 - jair.org
Contract scheduling is a general technique that allows the design of systems with
interruptible capabilities, given an algorithm that is not necessarily interruptible. Previous …

Further connections between contract-scheduling and ray-searching problems

S Angelopoulos - arXiv preprint arXiv:1504.07168, 2015 - arxiv.org
This paper addresses two classes of different, yet interrelated optimization problems. The
first class of problems involves a robot that must locate a hidden target in an environment …

Weighted online search

S Angelopoulos, K Panagiotou - Journal of Computer and System …, 2023 - Elsevier
We study the general setting of weighted search in which a number of weighted targets are
hidden in a star-like environment, and a mobile searcher must locate a subset of targets with …

Decision-Theoretic Approaches in Learning-Augmented Algorithms

S Angelopoulos, C Dürr, G Melidi - arXiv preprint arXiv:2501.17701, 2025 - arxiv.org
In this work, we initiate the systemic study of decision-theoretic metrics in the design and
analysis of algorithms with machine-learned predictions. We introduce approaches based …

Optimal scheduling of contract algorithms for anytime problem-solving

A López-Ortiz, S Angelopoulos, AM Hamel - Journal of Artificial Intelligence …, 2014 - jair.org
A contract algorithm is an algorithm which is given, as part of the input, a specified amount of
allowable computation time. The algorithm must then complete its execution within the …

[PDF][PDF] Earliest-Completion Scheduling of Contract Algorithms with End Guarantees.

S Angelopoulos, S Jin - IJCAI, 2019 - ijcai.org
We consider the setting in which executions of contract algorithms are scheduled in a
processor so as to produce an interruptible system. Such algorithms offer a trade off …

Alternative measures for the analysis of online algorithms

R Dorrigiv - 2010 - uwspace.uwaterloo.ca
In this thesis we introduce and evaluate several new models for the analysis of online
algorithms. In an online problem, the algorithm does not know the entire input from the …

Contract Scheduling with Distributional and Multiple Advice

S Angelopoulos, M Bienkowski, C Dürr… - arXiv preprint arXiv …, 2024 - arxiv.org
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 time …

Competitive sequencing with noisy advice

S Angelopoulos, D Arsénio, S Kamali - arXiv preprint arXiv:2111.05281, 2021 - arxiv.org
Several well-studied online resource allocation problems can be formulated in terms of
infinite, increasing sequences of positive values, in which each element is associated with a …

Further connections between contract-scheduling and ray-searching problems

S Angelopoulos - Journal of Scheduling, 2022 - Springer
This paper addresses two classes of different, yet interrelated optimization problems. The
first class of problems involves a mobile searcher that must locate a hidden target in an …
