Welcome to Concert Technology

Concert Technology offers a C++ library of classes and functions that enable you to design models of problems for both math programming (including linear programming, mixed integer programming, quadratic programming, and network programming) and constraint programming solutions.

This library is not a new programming language: it lets you use data structures and control structures provided by C++. Thus, the Concert Technology part of an application can be completely integrated with the rest of that application (for example, the graphic interface, connections to databases, etc.) because it can share the same objects.

Furthermore, you can use the same objects to model your problem whether you choose a constraint programming or math programming approach. In fact, Concert Technology enables you to combine these technologies simultaneously.

This manual assumes that you are familiar with the operating system where you are using Concert Technology. Since Concert Technology is written for C++ developers, this manual assumes that you can write C++ code and that you have a working knowledge of your C++ development environment.

Throughout this manual, the following typographic conventions apply:

• Samples of code are written in this typeface.
• The names of constructors and member functions appear in this typeface in the section where they are documented.
• Important ideas are emphasized like this.

The names of types, classes, and functions defined in the Concert Technology library begin with Ilo.

The names of classes are written as concatenated, capitalized words. For example:

IloNumVar

A lower case letter begins the first word in names of arguments, instances, and member functions. Other words in such a name begin with a capital letter. For example,

IloNumVarArray::setBounds

There are no public data members in Concert Technology.

Accessors begin with the keyword get followed by the name of the data member. Accessors for Boolean members begin with is followed by the name of the data member. Like other member functions, the first word in such a name begins with a lower case letter, and any other words in the name begin with a capital letter.

Modifiers begin with the keyword set followed by the name of the data member.

The Concert Technology 2.0 library comes with the following documentation. The online documentation, in HTML format, may be accessed through standard HTML browsers.

• The Reference Manual documents the predefined C++ classes, global functions, type definitions, and macros in the libraries. It also provides formal explanations of certain Concepts, such as arrays, handles, notification, and column-wise modeling.
• The README file, delivered in the standard distribution, contains the most current information about platform prerequisites for Concert Technology.
• Source code for examples is located in the examples directory in the standard distribution.

ILOG offers technical support, users' mailing lists, and comprehensive websites for its products, including Concert Technology, ILOG CPLEX, and ILOG Solver.

There are two kinds of web pages available to users of Concert Technology: web pages restricted to owners of a paid maintenance contract; web pages freely available to all.
