==================================================
< IloCplex::PreInd >
0 Off (do not use presolve) 1 On (use presolve) Default: 1
Description: Presolve indicator. When set to 1, invokes the CPLEX Presolve to simplify and reduce problems.
< 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.
