Description

Decides whether CPLEX will attempt to reformulate a MIQP or MIQCP model that contains only binary variables. When this feature is active, adjustments will be made to the elements of a quadratic matrix that is not nominally positive semi-definite (PSD, as required by CPLEX for all QP and most QCP formulations), to make it PSD, and CPLEX will also attempt to tighten an already PSD matrix for better numerical behavior. The default setting of 1 (one) means yes, CPLEX should attempt to reformulate, but you can turn it off if necessary; most models should benefit from the default setting.
