Speed-up Technique in Time-Varying Shortest Path Problems with Arbitrary Waiting Times [PDF]

open access: yesمدیریت مهندسی و رایانش نرم, 2020
Network flow problems are considered a vital branch of operations research. These problems are classified into static and time-varying classes. Network flow problems are time-varying in real application, because any flow must take a given amount of time ...

ON ASSOCIATIVE SHORTEST PATH PROBLEMS [PDF]

open access: yesBulletin of informatics and cybernetics, 1997
Summary: We consider a wide class of shortest path problems in acyclic digraphs. In the problems, the length of a path is defined by using an associative binary operation. We derive recursive equations in dynamic programming for the problems, which involve additive, multiplicative, multiplicative-additive, minimum and fractional shortest path problems.

The Capacity Expansion Path Problem in Networks

open access: yesJournal of Applied Mathematics, 2013
This paper considers the general capacity expansion path problem (GCEP) for the telecommunication operators. We investigate the polynomial equivalence between the GCEP problem and the constrained shortest path problem (CSP) and present a pseudopolynomial

Neutrosophic Shortest Path Problem (NSPP) in a Directed Multigraph [PDF]

open access: yesNeutrosophic 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 ...

“rsppfp”: An R package for the shortest path problem with forbidden paths

open access: yesSoftwareX, 2019
The Shortest Path Problem with Forbidden Paths (SPPFP) is a variant of the original shortest path problem, where the constraints come from a set of forbidden arc sequences that cannot be part of any feasible solution.

An Algorithm for the Cycled Shortest Path Problem [PDF]

open access: yesMuṭāli̒āt-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

A Hybrid Routing Approach Using Two Searching Layers

open access: yesElectrical, Control and Communication Engineering, 2021
This paper considers SUB_GOALs by using basic A* algorithm and Subgoal Graphs in a hybrid approach to execute optimal route. SUB_GOALs identified with pre-searching from basic A* at break points and Subgoal Graphs at corners of obstacles are added to ...

Dynamic Shortest Paths Methods for the Time-Dependent TSP

open access: yesAlgorithms, 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.

The Rough Interval Shortest Path Problem

open access: yes, 2021
The shortest path problem is one of the most popular network optimization problems and it is of great importance in areas such as transportation, network design or telecommunications. This model deals with determining a minimum weighted path between a pair of nodes of a given network.
