k-Strong Shortest Path Union Cover for Certain Graphs and Networks [PDF]
arXiv, 2021 The k-distance strong shortest path union cover of a graph is the minimum cardinality among all strong shortest path union cover at distance k of G. In this paper we determine the 2-strong shortest path union cover for certain graphs, also we prove that the k-strong shortest path union cover problem, in general, is NP-complete.

Dynamic Shortest Paths Methods for the Time-Dependent TSP
Algorithms, 2021 The time-dependent traveling salesman problem (TDTSP) asks for a shortest Hamiltonian tour in a directed graph where (asymmetric) arc-costs depend on the time the arc is entered.

How to Compose Shortest Paths [PDF]
arXiv, 2022 The composition problem for shortest paths asks the following: given shortest paths on weighted graphs M and N which share a common boundary, find the shortest paths on their union. This problem is a crucial step in any algorithm which uses the divide and conquer method to find shortest paths.

An Algorithm for the Cycled Shortest Path Problem [PDF]
Muṭāli̒āt-i Mudīriyyat-i Ṣan̒atī, 2011 For a network with cycle, where at least one cycle exists, the Floyd- Warshall algorithm is probably the most used algorithm to determine he least cost path between every pair of nodes on this network, i.e. the solution for the shortest path problem with

Neutrosophic Shortest Path Problem (NSPP) in a Directed Multigraph [PDF]
Neutrosophic Sets and Systems, 2019 One of the important non-linear data structures in Computer Science is graph. Most of the real life network, be it a road transportation network, or airlines network or a communication network etc., cannot be exactly transformed into a graph model, but ...

Shortest Reconfiguration of Perfect Matchings via Alternating Cycles [PDF]
, 2019 Motivated by adjacency in perfect matching polytopes, we study the shortest reconfiguration problem of perfect matchings via alternating cycles. Namely, we want to find a shortest sequence of perfect matchings which transforms one given perfect matching ...

The Shortest Path with Increasing Chords in a Simple Polygon [PDF]
arXiv, 2022 We study the problem of finding the shortest path with increasing chords in a simple polygon. A path has increasing chords if and only if for any points a, b, c, and d that lie on the path in that order, |ad| >= |bc|. In this paper we show that the shortest path with increasing chords is unique and present an algorithm to construct it.

Cellular Automata Applications in Shortest Path Problem
, 2017 Cellular Automata (CAs) are computational models that can capture the essential features of systems in which global behavior emerges from the collective effect of simple components, which interact locally.
