ILOG CPLEX 10.1 User's Manual > Discrete Optimization > Solving Mixed Integer Programming Problems (MIP) > Example: Reading a MIP Problem from a File

These examples show you how to solve a MIP with the Component Libraries when the problem data is stored in a file.

Complete Program: ilomipex2.cpp

This example derives from ilolpex2.cpp, an LP example explained in the manual ILOG CPLEX Getting Started. That LP example differs from this MIP example in these ways:

Like other applications based on ILOG CPLEX Concert Technology, this one uses IloEnv env to initialize the Concert Technology environment and IloModel model(env) to create a problem object. Before it ends, it calls env.end to free the environment.

Complete Program: mipex2.c

The example derives from lpex2.c, an LP example explained in the manual ILOG CPLEX Getting Started. That LP example differs from this MIP example in these ways:

Like other applications based on the ILOG CPLEX Callable Library, this one calls CPXopenCPLEX to initialize the ILOG CPLEX environment; it sets the screen-indicator parameter to direct output to the screen and calls CPXcreateprob to create a problem object. Before it ends, it calls CPXfreeprob to free the space allocated to the problem object and CPXcloseCPLEX to free the environment.
