ILOGCPLEX (Application)


The IBM ILOG CPLEX Optimization Studio provides the fastest way to build efficient optimization models and state-of-the-art applications for the full range of planning and scheduling problems. The Optimization Programming Language (OPL) provides a natural representation of optimization models, requiring far less effort than general-purpose programming languages. The Integrated Development Environment (IDE) makes it easy to evaluate different modeling approaches and to integrate external data. With its built-in development tools, it supports the entire model development process.

In addition to accessing the IBM ILOG CPLEX Optimizers for mathematical programming and constraint programming through the OPL language and IDE, IBM ILOG CPLEX Optimization Studio also provides access through the ILOG Concert Technology API in C++, Java, or Microsoft .NET, or through the CPLEX Callable Library.


Before using ILOG CPLEX for the first time one must submit a help ticket to request joining the SHARCNET ilogcplex group. The IBM ILOG CPLEX Optimization Studio software is made freely available on SHARCNET for non-commercial use through IBM’s Academic Initiative program and may only be used in accordance with the associated Software Usage Guidelines.
