Shortest Paths with Pairwise-Distinct Edge Labels: Finding Biochemical Pathways in Metabolic Networks [PDF]

open access: yesarXiv, 2010
A problem studied in Systems Biology is how to find shortest paths in metabolic networks. Unfortunately, simple (i.e., graph theoretic) shortest paths do not properly reflect biochemical facts. An approach to overcome this issue is to use edge labels and search for paths with distinct labels.

Constrained shortest paths and related problems

open access: yes, 2001
The classical shortest path problem, to find a path of minimal cost between two nodes in a graph, is efficiently solvable in polynomial time. However, in many applications we also have additional budget or resource constraints on a path. This problem is known as constrained shortest path problem and unfortunately belongs to the class of "hard" problems

Computing shortest paths in 2D and 3D memristive networks

open access: yes, 2013
Global optimisation problems in networks often require shortest path length computations to determine the most efficient route. The simplest and most common problem with a shortest path solution is perhaps that of a traditional labyrinth or maze with a ...

Computing L1 Shortest Paths among Polygonal Obstacles in the Plane [PDF]

open access: yesarXiv, 2012
Given a point $s$ and a set of $h$ pairwise disjoint polygonal obstacles of totally $n$ vertices in the plane, we present a new algorithm for building an $L_1$ shortest path map of size O(n) in $O(T)$ time and O(n) space such that for any query point $t$, the length of the $L_1$ shortest obstacle-avoiding path from $s$ to $t$ can be reported in $O(\log

Link distance and shortest path problems in the plane

open access: yesComputational Geometry, 2009
AbstractThis paper describes algorithms to compute Voronoi diagrams, shortest path maps, the Hausdorff distance, and the Fréchet distance in the plane with polygonal obstacles. The underlying distance measures for these algorithms are either shortest path distances or link distances.

Robust time-varying shortest path with arbitrary waiting time at vertices

open access: yesCroatian Operational Research Review, 2017
In this paper, we propose an algorithm for solving the robust time varying shortest path problem in which the waiting time at any vertex is not restricted. The problem is to find the shortest path connecting source node s and sink node i in a timevarying

A New Algorithm for the Discrete Shortest Path Problem in a Network Based on Ideal Fuzzy Sets [PDF]

open access: yesJournal of Optimization in Industrial Engineering, 2013
A shortest path problem is a practical issue in networks for real-world situations. This paper addresses the fuzzy shortest path (FSP) problem to obtain the best fuzzy path among fuzzy paths sets. For this purpose, a new efficient algorithm is introduced
