Controls presolve Q matrix linearization. Option 1 attempts to linearize quadratic constraints or a quadratic objective, potentially transforming an MIQP or MIQCP into an MILP. Option 0 shuts off the transformation. The default setting (-1) choose automatically. The automatic setting works well, but there are cases where forcing Q linearization can be beneficial.
