Note
|
This attribute represents the integral of the primal-dual gap over time. It measures the convergence of the best (dual) bound
BESTBOUND and the primal bound
MIPBESTOBJVAL over the whole solving time. Lower values are better. For details on the primal(-dual) integral see Berthold:
Measuring the impact of primal heuristics, OR Letters 41(6), pp. 611-614, 2013.
