Description

Limits the number of presolve passes that CPLEX makes during preprocessing. When this parameter is set to a nonzero value, invokes CPLEX presolve to simplify and reduce problems.

When this parameter is set to a positive value, presolve is applied the specified number of times, or until no more reductions are possible.

At the default value of -1, presolve should continue only if it seems to be helping.

When this parameter is set to zero, CPLEX does not apply presolve, but other reductions may occur, depending on settings of other parameters and specifics of your model.
