Exact Methods for the Split Delivery Vehicle Routing Problem With Two‐Dimensional Loading Constraints

open access: yesNetworks, Volume 86, Issue 4, Page 361-388, December 2025.
ABSTRACT The Split Delivery Vehicle Routing Problem with Two‐dimensional Loading Constraints (2L‐SDVRP) integrates vehicle routing, split delivery, and two‐dimensional packing constraints. In the 2L‐SDVRP, customers can be served by multiple vehicles, and their demands consist of different two‐dimensional rectangular items that must be packed in the ...

Fully dynamic all-pairs shortest paths with worst-case update-time revisited

open access: yes, 2016
We revisit the classic problem of dynamically maintaining shortest paths between all pairs of nodes of a directed weighted graph. The allowed updates are insertions and deletions of nodes and their incident edges.

The Metric Nearness Problem [PDF]

open access: yes, 2008
Metric nearness refers to the problem of optimally restoring metric properties to distance measurements that happen to be nonmetric due to measurement errors or otherwise.

Extending the Nested Parallel Model to the Nested Dataflow Model with Provably Efficient Schedulers

open access: yes, 2016
The nested parallel (a.k.a. fork-join) model is widely used for writing parallel programs. However, the two composition constructs, i.e. "$\parallel$" (parallel) and "$;$" (serial), are insufficient in expressing "partial dependencies" or "partial ...

Multi-Topology Routing Algorithms in SDN-Based Space Information Networks

open access: yesFuture Internet, 2019
Aiming at the complex structure of the space information networks (SIN) and the dynamic change of network topology, in order to design an efficient routing strategy, this paper establishes a SIN management architecture based on Software-defined ...

Dynamic impedance model based two‐stage customized charging–navigation strategy for electric vehicles

open access: yesEnergy Conversion and Economics, 2023
With the continuously increasing penetration of electric vehicles (EVs), the mutual match between the distribution of charging resources and the spatial–temporal distribution of EV charging demands is becoming increasingly important.

Improving The Floyd-Warshall All Pairs Shortest Paths Algorithm

open access: yes, 2021
The Floyd-Warshall algorithm is the most popular algorithm for determining the shortest paths between all pairs in a graph. It is very a simple and an elegant algorithm. However, if the graph does not contain any negative weighted edge, using Dijkstra's shortest path algorithm for every vertex as a source vertex to produce all pairs shortest paths of ...

Identifying the Shortest Path of a Semidirected Graph and Its Application

open access: yesMathematics, 2022
The basic goal of this research is to find the shortest path of a semidirected graph and apply it to the road network system. In the field of graph theory, networks are described as directed graphs, undirected graphs, or a combination of both.
