title: Implementation and Results of a "Generating Small Instances with Interesting Features for the Traveling Salesperson Problem"

description: 1. Introduction

In this archive, we provide the implementation and experimental of a generator for small Traveling Salesperson Problem instances as well as the results of a Randomized Local Search (RLS) with and without FFA applied to the generated instances.

These are the data used in the paper below, which contains the exact specification of all algorithms, objective functions, and the encoding we applied.

Tianyu Liang, Zhize Wu, Matthias Thürer, Markus Wagner, and Thomas Weise. Generating Small Instances with Interesting Features for the Traveling Salesperson Problem. In 16th International Conference on Evolutionary Computation Theory and Applications (ECTA'24), part of the 16th International Joint Conference on Computational Intelligence (IJCCI'24). November 20-24, 2024. Porto, Portugal. Setúbal, Portugal: SciTePress.

To run the experiments, you need moptipyapps and moptipy, which contain the actual algorithm implementations. Both packages are available on GitHub and on PyPI. However, we include several versions of them in the folder source/packages, just in case.

2. Directory Structure

This archive contains the following directories:



source contains the Python source codes needed to run the experiment.

source/packages contains the source codes of the Python packages with the actual algorithm implementations.

source/experiment_execution_scripts contains the scripts to run the experiments and to generate the instances.

results is the directory with the results, i.e., with the log files generated by the experiment.

evaluator is the folder containing Python scripts that were used to evaluate these results.

evaluation was generated using the evaluation scripts and contains tables and figures and a result summary in CSV format.
