added MINLPLib2 and its subsets of (non)convex problems as test sets #69

Closed jakobwitzig closed 6 years ago

Obviously, the test set MINLPLIB2 is a disjoint union of the convex and the nonconvex part. I suggest to list only the convex and nonconvex parts explicitly, and then add another item MINLPLIB2 that combines the two.

For an example, see how the test set MMM is composed.

Obviously, ...

No, this neither obvious nor correct. There are instances, e.g., arki0018, for which it is only known that the objective curvature is nonconcave whereas the constraint curvature is linear. So it is neither nonconvex nor proven to be convex.

Then, it may as well stay as it is.
