If you follow the link to a test set you will find further information about the instances like origin, optimal values, and some difficulty classification.

The bullet behind the name of the set is an indication of the status of
the set.
means *dead*.
There are various publications where these instances are solved.
means *solved*. All the problem in the set are solved, but there are
not at least two independent publications.
means *unsolved*.
There are problem in the set were the optimal value is not
known.
