Lower Bounds on the Generalized Traveling Salesman Problem with Neighborhoods

Overview

This repository provides instances of the Generalized Traveling Salesman Problem with Neighborhoods (GTSPN) studied in the article:

@article{deckerova24eswa,
  author    = {Jindřiška Deckerová, Petr Váňa, and Jan Faigl},
  title     = {{Combinatorial Lower Bounds for the Generalized Traveling Salesman Problem with Neighborhoods}},
  journal = {Expert Systems with Applications},
  volume = {258},
  pages = {125185},
  year = {2024},
  issn = {0957-4174},
  doi = {https://doi.org/10.1016/j.eswa.2024.125185}
}

GTSPN Instances

The provided instances are derived from GTSPN instances [1]. The derived 3D instances are available in /instances/GTSPN-3D. And the derived 7D instances are available in /instances/GTSPN-7D.

Source codes

The B&B method is implemenented in julia programming language. The implementation is in folder src. To run the method, first, julia packages need to be installed, e.g., using install-julia-packages.sh. The parameters can be adjusted in src/bnb.ini. The method is run as julia src/bnb-api.jl.

Results

The computational results reported in [deckerova24eswa] are summarized in results.csv.
