Pseudo boolean optimization problems converted from MINLPLIB2 [1].
Some notes on instances
-----------------------
### sporttournament*.opb
The objective functions are scaled by -1 to turn maximization
problems into minimization problems.
### cardqp_iqp.opb
The objective function is scaled by 200000000 to turn fractional
coefficients into integers.
### cardqp_inlp.opb
The objective function is scaled by 200000000 to turn fractional
coefficients into integers.
### faclay80.opb
