Local Advice and Local Decompression

A Balliu, S Brandt, F Kuhn, K Nowicki, D Olivetti… - arXiv preprint arXiv …, 2024 - arxiv.org
Algorithms with advice have received ample attention in the distributed and online settings,
and they have recently proven useful also in dynamic settings. In this work we study local …

Deterministic graph exploration with advice

B Gorain, A Pelc - ACM Transactions on Algorithms (TALG), 2018 - dl.acm.org
We consider the fundamental task of graph exploration. An n-node graph has unlabeled
nodes, and all ports at any node of degree d are arbitrarily numbered 0,…, d− 1. A mobile …

Constant-length labeling schemes for deterministic radio broadcast

F Ellen, B Gorain, A Miller, A Pelc - ACM Transactions on Parallel …, 2021 - dl.acm.org
Broadcast is one of the fundamental network communication primitives. One node of a
network, called the s ource, has a message that has to be learned by all other nodes. We …

Advice complexity of treasure hunt in geometric terrains

A Pelc, RN Yadav - Information and Computation, 2021 - Elsevier
Treasure hunt is finding an inert target by a mobile agent. We consider treasure hunt in
polygonal terrains with polygonal obstacles. The agent finds the treasure when there is a …

Edge exploration of anonymous graph by mobile agent with external help

AK Dhar, B Gorain, K Mondal, S Patra, RR Singh - Computing, 2023 - Springer
Exploration of an unknown network by one or multiple mobile entities is a well studied
problem which has various applications like treasure hunt, collecting data from some node …

Brief Announcement: Local Advice and Local Decompression

A Balliu, S Brandt, F Kuhn, K Nowicki, D Olivetti… - 2024 - publications.cispa.de
In this work we study local computation with advice: the goal is to solve a graph problem $\Pi
$ with a distributed algorithm in $ f (\Delta) $ communication rounds, for some function $ f …

Cost vs. information tradeoffs for treasure hunt in the plane

A Pelc, RN Yadav - arXiv preprint arXiv:1902.06090, 2019 - arxiv.org
A mobile agent has to find an inert treasure hidden in the plane. Both the agent and the
treasure are modeled as points. This is a variant of the task known as treasure hunt. The …

Impact of knowledge on election time in anonymous networks

Y Dieudonné, A Pelc - Proceedings of the 29th ACM Symposium on …, 2017 - dl.acm.org
Leader election is one of the basic problems in distributed computing. This is a symmetry
breaking problem: all nodes of a network must agree on a single node, called the leader. If …

Short labeling schemes for topology recognition in wireless tree networks

B Gorain, A Pelc - International Colloquium on Structural Information and …, 2017 - Springer
We consider the problem of topology recognition in wireless (radio) networks modeled as
undirected graphs. Topology recognition is a fundamental task in which every node of the …

Finding the size and the diameter of a radio network using short labels

B Gorain, A Pelc - Theoretical Computer Science, 2021 - Elsevier
The number of nodes of a network, called its size, and the largest distance between nodes of
a network, called its diameter, are among the most important network parameters. Knowing …
