Optimal linear tracking for a hidden target on one of K-intervals

FS Alamri, MAA El-Hadidy - Journal of Engineering Mathematics, 2024 - Springer
In this paper, we consider one of the most important missing target search problems, in
which the bounded linear search interval has been divided into a number of small sub …

Online search with a hint

S Angelopoulos - Information and Computation, 2023 - Elsevier
We introduce the study of search problems, in a setting in which the searcher has some
information, or hint concerning the hiding target. In particular, we focus on one of the …

A study on the existence of a cooperative search method with reducing the first metting time between one of several nano-sensors and a Brownian particle

MAA El-Hadidy, AA Alzulaibani - Afrika Matematika, 2024 - Springer
The coordinated search method for a one-dimensional Brownian particle in the fluid is
investigated in this paper. This technique helps to remove pollutants and impurities from the …

Search Games with Predictions

S Angelopoulos, T Lidbetter, K Panagiotou - arXiv preprint arXiv …, 2024 - arxiv.org
We study search games between a mobile Searcher and an immobile Hider in which the
Searcher aims to minimize some payoff, which is either the time to find the Hider (the search …

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 …

Discrete search stability for a hidden target on M-intervals with a known probabilistic distributed effort.

MAA El-Hadidy - Discrete Mathematics, Algorithms & …, 2025 - search.ebscohost.com
We consider a discrete search problem to detect a hidden target on one of the M-intersected
real lines at the origin. The target position is a vector of independent random variables with a …

A competitive search game with a moving target

B Duvocelle, J Flesch, M Staudigl… - European Journal of …, 2022 - Elsevier
We introduce a discrete-time search game, in which two players compete to find an invisible
object first. The object moves according to a time-varying Markov chain on finitely many …

The Faulty Satnav (GPS) Problem: Search for home in networks with unreliable directions

S Alpern - Theoretical Computer Science, 2023 - Elsevier
A Searcher wants to find the Home node on a given Network, but his directions are
unreliable. At every branch node of a network Q, a Satnav (GPS) points to the arc leading to …

Online routing and searching on graphs with blocked edges

D Shiri, H Tozan - Journal of Combinatorial Optimization, 2022 - Springer
We study routing and searching decisions of a search-and-detection (SDT) team on a road
network under online uncertainty setting. Given an undirected edge-weighted bounded …

A Booby Trap Game

T Lidbetter, K Lin - arXiv preprint arXiv:2412.01688, 2024 - arxiv.org
This paper presents a booby trap game played between a defender and an attacker on a
search space, which may be a compact subset of Euclidean space or a network. The …
