is this kind of like “if the answer to your minimization problem is negative infinity, the answer is undefined behavior”?
Yes, it picked a valid result and gave up.
I got a similar nonsensical result in my run-ins[1] in with SAT solvers too, until I added a lowerbound=0.
The "real life" follow-up question in interviews was how to minimize the total number of intermediate rows for a series of joins within in a cost-based optimizer.
