Heuristic sub-model options

The heuristic sub-model parameters can only be set using a Parameter File. The syntax for the parameters that influence the heuristic sub-model CPLEX solves is the following: SUB_<parameter> where <parameter> refers to the ODH-CPLEX name in the second table above. The syntax for the parameters that influence the heuristic sub-model CPLEX solves in Phase I is the following: PHASE1_<parameter>.

For example, SUB_CPX_RINSHEUR specifies the RINS heuristic frequency for CPLEX if it used to solve a heuristic sub-model, while PHASE1_CPX_RINSHEUR specifies the RINS heuristic frequency for CPLEX if it used to solve a heuristic sub-model in Phase I.
