An Adaptive Large Neighborhood Search for the Multiple Traveling Salesman Problem With Backup Coverage

IEEE Access
The Multiple Traveling Salesman Problem with Backup Coverage (mTSP-BC) is a vehicle routing variant in which all vehicles must remain within a maximum pairwise distance at every instant during their traversal, imposing spatiotemporal interdependence ...

Beyond Visual Scoring: Computational Computed Tomography Analysis for High‐Resolution Computed Tomography–Based Quantification of Interstitial Lung Disease in Inflammatory Rheumatic Disease

Arthritis Care &Research, EarlyView.
Interstitial lung disease (ILD) is a significant cause of morbidity and mortality in patients with inflammatory rheumatic disorders (IRDs). High‐resolution computed tomography (HRCT) is widely considered the gold standard for the noninvasive assessment of ILD; however, its interpretation is constrained by substantial interobserver variability and the ...

Constrained Optimization and Dynamic Trade-Off Method for Formation Assignment of Heterogeneous UAV Swarms

Drones
This paper addresses the formation assignment problem for heterogeneous UAV swarms in dynamic mission environments. A constrained optimization model is constructed in which UAV capabilities are divided into shareable and exclusive types; a neighborhood ...

Patients improve, patterns persist: longitudinal stability of RA joint involvement patterns

Arthritis Care &Research, Accepted Article.
Objective Rheumatoid arthritis is a heterogeneous disease. Data‐driven approaches, from synovial histology to joint involvement patterns (JIPs), have sought to define clinically meaningful subgroups. Whether these subgroups represent stable phenotypes or transient disease states remains unclear.

Adaptive Large Neighborhood Search for Mixed Integer Programming

, 2018
Large Neighborhood Search (LNS) heuristics are among the most powerful but also most expensive heuristics for mixed integer programs (MIP). Ideally, a solver learns adaptively which LNS heuristics work best for the MIP problem at hand in order to ...

A variable neighborhood-based heuristic for the heterogeneous fleet vehicle routing problem [PDF]

, 2008
The heterogeneous fleet vehicle routing problem is investigated using some adaptations of the variable neighborhood search (VNS). The initial solution is obtained by Dijkstra's algorithm based on a cost network constructed by the sweep algorithm and the ...
