< IloCplex::PrePass >

-1 Determined automatically
0 Do not use Presolve
or, any positive integer

Default: -1

Description: Limit on the number of Presolve passes made.
When set to a nonzero value, invokes the CPLEX Presolve to simplify and reduce problems.
When set to a positive value, the 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.
