Permutation Flow-shop : Taillard and VFR benchmarks best known solutions (updated according to linked report)

This dataset completes the report of the same author (Olivier Brunner) that can be viewed at : https://doi.org/10.5281/zenodo.15696776

It is composed of three consistant CSV files -  i.e. with the same columns.

The report abstract is :

This report presents solutions that, as of the date of publication, improve the cost (makespan) for 52 instances of the Permutation Flow-Shop Problem (PFSP) proposed by Eric Taillard or by Eva Vallada, Rubén Ruiz, and Jose M. Framinan. This report may help those who assess the quality of heuristics based on their ability to approach the best-known solutions. Three algorithmic techniques used are also presented: the super-prohibition sieve excluding paths with weights exceeding a given bound, the adaptive compartmental neighborhood with selective 2-closing, and finally the makespan calculation performed using upper-windowed multi-numbers.

The same versioning is used for the report and for the dataset. The dataset was created and starts at version 5 of the report.
