Problems on Shortest k-Node Cycles and Paths

open access: yesКібернетика та комп'ютерні технології, 2021
The paper is devoted to the construction of mathematical models for problems on the shortest cycles and paths, that pass through a given number of nodes of a directed graph.

Reconfiguring Shortest Paths in Graphs. [PDF]

open access: yesAlgorithmica, 2022
AbstractReconfiguring two shortest paths in a graph means modifying one shortest path to the other by changing one vertex at a time so that all the intermediate paths are also shortest paths. This problem has several natural applications, namely: (a) repaving road networks, (b) rerouting data packets in a synchronous multiprocessing setting, (c) the ...

Shortest Paths in a Hybrid Network Model [PDF]

open access: yesACM-SIAM Symposium on Discrete Algorithms, 2019
We introduce a communication model for hybrid networks, where nodes have access to two different communication modes: a local mode where communication is only possible between specific pairs of nodes, and a global mode where communication between any ...

On the Structure of Unique Shortest Paths in Graphs [PDF]

open access: yesACM-SIAM Symposium on Discrete Algorithms, 2018
This paper develops a structural theory of unique shortest paths in real-weighted graphs. Our main goal is to characterize exactly which sets of node sequences, which we call path systems, can appear as unique shortest paths in a graph with arbitrary ...

Shortest Paths Avoiding Forbidden Subpaths [PDF]

open access: yes, 2009
In this paper we study a variant of the shortest path problem in graphs: given a weighted graph G and vertices s and t, and given a set X of forbidden paths in G, find a shortest s-t path P such that no path in X is a subpath of P.

Shortest‐path network interdiction

open access: yesNetworks, 2002
AbstractWe study the problem of interdicting the arcs in a network in order to maximize the shortest s–t path length. “Interdiction” is an attack on an arc that destroys the arc or increases its effective length; there is a limited interdiction budget.
