A Simpler and More Efficient Algorithm for the Next-to-Shortest Path Problem [PDF]
, 2011 Given an undirected graph $G=(V,E)$ with positive edge lengths and two vertices $s$ and $t$, the next-to-shortest path problem is to find an $st$-path which length is minimum amongst all $st$-paths strictly longer than the shortest path length.

Interval Type 2 Fuzzy Set in Fuzzy Shortest Path Problem
Mathematics, 2016 The shortest path problem (SPP) is one of the most important combinatorial optimization problems in graph theory due to its various applications. The uncertainty existing in the real world problems makes it difficult to determine the arc lengths exactly.

Shortest Path from Bandar Tun Razak to Berjaya Times Square using Dijkstra Algorithm
Journal of Computing Research and Innovation, 2020 The shortest path is an issue that involves the route from one point (nodes) to another. It is to find a path with a minimum travelling time. Nowadays, traffic problems have affected many transport users especially in Kuala Lumpur area.

An Effective Genetic Algorithm for Solving the Clustered Shortest-Path Tree Problem
IEEE Access, 2021 The clustered shortest-path tree problem (CluSPTP) is an extension of the classical single-source shortest-path problem, in which, given a graph with the set of nodes partitioned into a predefined, mutually exclusive and exhaustive set of clusters, we ...

A Novel Method for Solving Multi-objective Shortest Path Problem in Respect of Probability Theory
Tehnički Glasnik, 2023 Transportation process or activity can be considered as a multi-objective problem reasonably. However, it is difficult to obtain an absolute shortest path with optimizing the multiple objectives at the same time by means of Pareto approach. In this paper,

A Pathfinding Problem for Fork-Join Directed Acyclic Graphs with Unknown Edge Length
Algorithms, 2021 In a previous paper by the author, a pathfinding problem for directed trees is studied under the following situation: each edge has a nonnegative integer length, but the length is unknown in advance and should be found by a procedure whose computational ...

Analysis of Dijkstra’s Algorithm and A* Algorithm in Shortest Path Problem
Journal of Physics: Conference Series, 2020 Finding the shortest path in direction effective is essential. To solve this shortest path problem, we usually using Dijkstra or A* algorithm. These two algorithms are often used in routing or road networks. This paper’s objective is to compare those two

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 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.

A spectral approach to the shortest path problem [PDF]
Linear Algebra and its Applications, 2021 Let $G=(V,E)$ be a simple, connected graph. One is often interested in a short path between two vertices $u,v$. We propose a spectral algorithm: construct the function $ϕ:V \rightarrow \mathbb{R}_{\geq 0}$ $$ ϕ= \arg\min_{f:V \rightarrow \mathbb{R} \atop f(u) = 0, f \not\equiv 0} \frac{\sum_{(w_1, w_2) \in E}{(f(w_1)-f(w_2))^2}}{\sum_{w \in V}{f(w)^2}}.
