C++ tutorial

This tutorial shows you how to write C++ applications using CPLEX with Concert Technology. In this tutorial you will learn about:

The design of CPLEX in Concert Technology C++ applications
CPLEX objects are necessary to an application in C++.
Compiling CPLEX in Concert Technology C++ applications
When you compile a C++ application with a C++ library like CPLEX in Concert Technology, you need to tell your compiler where to find the CPLEX and Concert include files (that is, the header files), and you also need to tell the linker where to find the CPLEX and Concert libraries. The sample projects and makefiles illustrate how to carry out these crucial steps for the examples in the standard distribution. They use relative path names to indicate to the compiler where the header files are, and to the linker where the libraries are.
The anatomy of a Concert Technology C++ application
Concert Technology is a C++ class library, and therefore Concert Technology applications consist of interacting C++ objects. This topic gives a short introduction to the most important classes that are usually found in a complete Concert Technology CPLEX C++ application.
Building and solving a small LP model in C++
This sample solves a linear programming model in C++.
Writing and reading models and files
CPLEX supports reading models from files and writing models to files in a C++ application.
Selecting an optimizer
Select an optimizer in a C++ application on the basis of the problem type.
Reading a problem from a file: example ilolpex2.cpp
The sample ilolpex2.cpp illustrates reading a model from a file in a C++ application.
Modifying and re-optimizing
CPLEX offers means to modify the model and re-optimize, using available information from previous optimizations.
Modifying an optimization problem: example ilolpex3.cpp
The sample ilolpex3.cpp shows how to modify a model so that CPLEX can re-optimize and re-use any information available from previous optimizations.
