About This Manual

The ILOG CPLEX Component Libraries are designed to facilitate the development of applications to solve, modify, and interpret the results of linear, mixed integer, continuous convex quadratic, quadratically constrained, and mixed integer quadratic or quadratically constrained programming.

The ILOG CPLEX Component Libraries consist of:

• the CPLEX Callable Library, a C application programming interface (API), and
• ILOG Concert Technology, an object-oriented API for C++, Java, and C#.NET users.

ILOG Concert Technology is also part of ILOG Solver, enabling cooperative strategies using CPLEX and Solver together for solving difficult optimization problems.

This manual assumes that you are familiar with the operating system on which you are using ILOG CPLEX.

The CPLEX Callable Library is written in the C programming language. The Concert Technology libraries are written in the C++, Java, and C#.NET programming languages. If you use these products, this manual assumes you can write code in the appropriate language, and that you have a working knowledge of a supported integrated development environment (IDE) for that language.

Throughout this manual:

• The names of routines and parameters defined in the CPLEX Callable Library begin with CPX. The names of classes and functions defined in Concert Technology C++ API begin with Ilo. This convention helps prevent name space conflicts with user-written routines and other code libraries.
• The names of Component Library classes, functions, routines, and routine arguments appear in this typeface (examples: CPXprimopt, numcols, IloCplex::solveFixed).

In addition to this Reference Manual documenting C and C++, ILOG CPLEX also comes with these resources:

• Getting Started with ILOG CPLEX introduces you to ways of specifying models and solving problems with ILOG CPLEX.
• The ILOG CPLEX User's Manual explores programming with ILOG CPLEX in greater depth. It provides practical ideas about how to use CPLEX in your own applications and shows how and why design and implementation decisions in the examples were made.
• The ILOG CPLEX Release Notes highlight the new features and important changes in this version.
• The ILOG CPLEX Java Reference Manual supplies detailed definitions of the Concert Technology Java interfaces and ILOG CPLEX Java classes.
• The ILOG CPLEX C#.NET Reference Manual supplies detailed definitions of the Concert Technology C#.NET interfaces and ILOG CPLEX C#.NET classes.
• Source code for examples is delivered in the standard distribution.
• A readme.html file is delivered in the standard distribution. This file contains the most current information about platform prerequisites for ILOG CPLEX.

All of the manuals and Release Notes are available in online versions. The online documentation, in HTML format, can be accessed through standard HTML browsers.
