Where can we find the last evaluation in bbob data?

[nikohansen]

Observations from five different data sets:

1. The last evaluation can always be found in the .info files, in the line that points to the .dat file. The best f-value is given with two digits of precision only.
2. In data sets from 2009, 2015, 2022, 2023 from the archive: the .tdat file contains the last evaluation, the .dat file does not.
3. A data set I generated in December 2025: the .dat and .tdat files contain the last evaluation.

I think this should be corrected in case we would ever re-archive the data. Preferably, each and every data file should contain the last evaluation of the run.

When (since which version) did this change in the code? EDIT: since v2.6.101.

I don't understand - the data generated in December 2025 contains the last evaluation in both the .dat and .tdat files. Is this not what you want? What should be corrected?

The change was done in this commit: e688fe8

In case we would ever re-archive the data, any data files that do not have this entry should be corrected. Ideally, there should be no .dat file to be found in our archives without the last evaluation line.

This is in order prevent users playing with our data to get somewhat misleading results. This is what is currently happening in the OpenOpt project: the last entry is not in the (provisory?) data base.

All clear.
