Anytime search in dynamic graphs

M Likhachev, D Ferguson, G Gordon, A Stentz… - Artificial Intelligence, 2008 - Elsevier
Agents operating in the real world often have limited time available for planning their next
actions. Producing optimal plans is infeasible in these scenarios. Instead, agents must be …

Improved dynamic graph coloring

S Solomon, N Wein - ACM Transactions on Algorithms (TALG), 2020 - dl.acm.org
This article studies the fundamental problem of graph coloring in fully dynamic graphs. Since
the problem of computing an optimal coloring, or even approximating it to within n1-ε for any …

Parallel batch-dynamic algorithms for k-core decomposition and related graph problems

QC Liu, J Shi, S Yu, L Dhulipala, J Shun - Proceedings of the 34th ACM …, 2022 - dl.acm.org
Maintaining a k-core decomposition quickly in a dynamic graph has important applications
in network analysis. The main challenge for designing efficient exact algorithms is that a …

Adaptive Out-Orientations with Applications

C Chekuri, AB Christiansen, J Holm… - Proceedings of the 2024 …, 2024 - SIAM
We give improved algorithms for maintaining edge-orientations of a fully-dynamic graph,
such that the maximum out-degree is bounded. On one hand, we show how to orient the …

Batch dynamic single-source shortest-path algorithms: An experimental study

R Bauer, D Wagner - International Symposium on Experimental Algorithms, 2009 - Springer
A dynamic shortest-path algorithm is called a batch algorithm if it is able to handle graph
changes that consist of multiple edge updates at a time. In this paper we focus on fully …

Adaptive out-orientations with applications

ABG Christiansen, J Holm, I van der Hoog… - arXiv preprint arXiv …, 2022 - arxiv.org
We give improved algorithms for maintaining edge-orientations of a fully-dynamic graph,
such that the out-degree of each vertex is bounded. On one hand, we show how to orient the …

Explicit and implicit dynamic coloring of graphs with bounded arboricity

M Henzinger, S Neumann, A Wiese - arXiv preprint arXiv:2002.10142, 2020 - arxiv.org
Graph coloring is a fundamental problem in computer science. We study the fully dynamic
version of the problem in which the graph is undergoing edge insertions and deletions and …

[PDF][PDF] A GIS-based dynamic shortest path determination in emergency vehicles

S Panahi, MR Delavar - World applied sciences journal, 2008 - Citeseer
Accomplishing an effective routing of emergency vehicle will minimize its response time and
will thus improve the response performance. Traffic congestion is a critical problem in urban …

Certifying fully dynamic algorithms for recognition and hamiltonicity of threshold and chain graphs

J Beisegel, E Köhler, R Scheffler, M Strehler - Algorithmica, 2023 - Springer
Solving problems on graphs dynamically calls for algorithms to function under repeated
modifications to the graph and to be more efficient than solving the problem for the whole …

[PDF][PDF] Ready to order?: on vertex and edge orderings of graphs

R Scheffler - 2023 - opus4.kobv.de
Vertex and edge orderings of graphs are commonly used in algorithmic graph theory. Such
orderings can encode structural properties of graphs in a condensed way and, thus, they …
