ILOG CPLEX 11.0 User's Manual

●●Then call CPXprimopt to optimize that problem.Then use CPXsolution to get a solution to the fixed problem.Example: Reading a MIP Problem from a FileThese examples show you how to solve a MIP with the Component Libraries when theproblem data is stored in a file.ilomipex2.cppThis example derives from ilolpex2.cpp, an LP example explained in the manualILOG CPLEX Getting Started. That LP example differs from this MIP example in theseways:◆This example solves only MIPs, so it calls only IloCplex::solve, and its commandline does not require the user to indicate an optimizer.◆ This example does not generate or print a basis.Like other applications based on ILOG CPLEX Concert Technology, this one uses IloEnvenv to initialize the Concert Technology environment and IloModel model(env) tocreate a problem object. Before it ends, it calls env.end to free the environment.mipex2.cThe example derives from lpex2.c, an LP example explained in the manual ILOG CPLEXGetting Started. That LP example differs from this MIP example in these ways:◆◆This example solves only MIPs, so it calls only CPXmipopt, and its command line doesnot require the user to indicate an optimizer.This example does not generate or print a basis.Like other applications based on the ILOG CPLEX Callable Library, this one callsCPXopenCPLEX to initialize the ILOG CPLEX environment; it sets the screen-indicatorparameter to direct output to the screen and calls CPXcreateprob to create a problemobject. Before it ends, it calls CPXfreeprob to free the space allocated to the problemobject and CPXcloseCPLEX to free the environment.300 ILOG CPLEX 11.0 — USER’ S MANUAL
