Near-shortest and K-shortest simple paths [PDF]

open access: yesNetworks, 2005
Summary: We present a new algorithm for enumerating all near-shortest simple (loopless) \(s\)-\(t\) paths in a graph \(G=(V,E)\) with nonnegative edge lengths. Letting \(n=|V|\) and \(m=|E|\), the time per path enumerated is \(O(nS(n,m))\) given a user-selected short-est-path subroutine with complexity \(O(S(n,m))\).

Multiple Object Tracking Using K-Shortest Paths Optimization [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2011
Multi-object tracking can be achieved by detecting objects in individual frames and then linking detections across frames. Such an approach can be made very robust to the occasional detection failure: If an object is not detected in a frame but is in previous and following ones, a correct trajectory will nevertheless be produced.

Finding k-shortest paths with limited overlap [PDF]

open access: yesThe VLDB Journal, 2020
AbstractIn this paper, we investigate the computation of alternative paths between two locations in a road network. More specifically, we study the k-shortest paths with limited overlap ($$k\text {SPwLO}$$ k SPwLO ) problem that aims at finding a set of k ...

Finding $k$ Simple Shortest Paths and Cycles [PDF]

open access: yes, 2016
The problem of finding multiple simple shortest paths in a weighted directed graph $G=(V,E)$ has many applications, and is considerably more difficult than the corresponding problem when cycles are allowed in the paths. Even for a single source-sink pair,

A genetic algorithm for finding the k shortest paths in a network

open access: yesEgyptian Informatics Journal, 2010
Most of the multimedia applications require the k shortest paths during the communication between a single source and multiple destinations. This problem is known as multimedia multicast routing and has been proved to be NP-complete. The paper proposes a

The Optimized Algorithm of Finding the Shortest Path in a Multiple Graph

open access: yesМоделирование и анализ информационных систем, 2023
In this paper, we study undirected multiple graphs of any natural multiplicity $k>1$. There are edges of three types: ordinary edges, multiple edges and multi-edges. Each edge of the last two types is a union of $k$ linked edges, which connect 2 or $(k+1)

Efficiently listing bounded length st-paths [PDF]

open access: yes, 2014
The problem of listing the $K$ shortest simple (loopless) $st$-paths in a graph has been studied since the early 1960s. For a non-negatively weighted graph with $n$ vertices and $m$ edges, the most efficient solution is an $O(K(mn + n^2 \log n ...

A Constrained Time-Dependent K Shortest Paths Algorithm Addressing Overlap and Travel Time Deviation

open access: yesInternational Journal of Transportation Science and Technology, 2015
Theoretical research often assumes all users are homogeneous in their route choice decision and will always pick the route with the shortest travel cost, which is not necessarily the case in reality. This paper documents the research effort in developing

Driver Route Planning Method Based on Accident Risk Cost Prediction

open access: yesJournal of Advanced Transportation, 2022
The number of cars on roadways around the world continues to increase year over year. However, the imbalance between traffic supply and demand has not only brought traffic congestion but also caused serious safety problems.
