Competitive Sequencing with Noisy Advice

Spyros Angelopoulos, Diogo Arsénio, Shahin Kamali

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…

Online Search with Maximum Clearance

Spyros Angelopoulos, Malachi Voss

We study the setting in which a mobile agent must locate a hidden target in a bounded or unbounded environment, with no information about the hider's position. In particular, we co…

Contract Scheduling With Predictions

Spyros Angelopoulos, Shahin Kamali

Contract scheduling is a general technique that allows to design a system with interruptible capabilities, given an algorithm that is not necessarily interruptible. Previous work o…

Online Search With a Hint

Spyros Angelopoulos

The linear search problem, informally known as the cow path problem, is one of the fundamental problems in search theory. In this problem, an immobile target is hidden at some unkn…

Competitive Search in a Network

Spyros Angelopoulos, Thomas Lidbetter

We study the classic problem in which a Searcher must locate a hidden point, also called the Hider in a network, starting from a root point. The network may be either bounded or un…

Interruptible Algorithms for Multiproblem Solving

Spyros Angelopoulos, Alejandro Lopez-Ortiz

In this paper we address the problem of designing an interruptible system in a setting in which problem instances, all equally important, must be solved concurrently. The syste…
