TD-H2H: Shortest Path Query on Time-Dependent Graphs [PDF]
Jisuanji kexue yu tansuo, 2023 A shortest path query on road networks is a fundamental problem, which has been studied widely. Existing studies usually model road networks as a static graph and query the path with the shortest distance between given vertices.

On the Quadratic Shortest Path Problem [PDF]
, 2015 Finding the shortest path in a directed graph is one of the most important combinatorial optimization problems, having applications in a wide range of fields. In its basic version, however, the problem fails to represent situations in which the value of the objective function is determined not only by the choice of each single arc, but also by the ...

Study on single-valued neutrosophic graph with application in shortest path problem
CAAI Transactions on Intelligence Technology, 2020 Fuzzy set and neutrosophic set are two efficient tools to handle the uncertainties and vagueness of any real-world problems. Neutrosophic set is more useful than fuzzy set (intuitionistic fuzzy sets) to manage the uncertainties of a real-life problem ...

Finding next-to-shortest paths in a graph [PDF]
, 2004 We study the problem of finding the next-to-shortest paths in a graph. A next-to-shortest $(u,v)$-path is a shortest $(u,v)$-path amongst $(u,v)$-paths with length strictly greater than the length of the shortest $(u,v)$-path.

Expected Length of the Shortest Path of the Traveling Salesman Problem in 3D Space
Journal of Advanced Transportation, 2022 Finding the shortest path of the traveling salesman problem (TSP) is a typical NP-hard problem and one of the basic optimization problems. TSP in three-dimensional space (3D-TSP) is an extension of TSP. It plays an important role in the fields of 3D path

Shortest Paths Avoiding Forbidden Subpaths [PDF]
, 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.

A Multi Objective Programming Approach to Solve Integer Valued Neutrosophic Shortest Path Problems [PDF]
Neutrosophic Sets and Systems, 2019 Neutrosophic (NS) set hypothesis gives another way to deal with the vulnerabilities of the shortest path problems (SPP). Several researchers have worked on fuzzy shortest path problem (FSPP) in a fuzzy graph with vulnerability data and completely ...

On Dynamic Shortest Paths Problems [PDF]
Algorithmica, 2004 We obtain the following results related to dynamic versions of the shortest-paths problem: Reductions that show that the incremental and decremental single-source shortest-paths problems, for weighted directed or undirected graphs, are, in a strong sense, at least as hard as the static all-pairs shortest-paths problem.
