CMPL (<Coliop|Coin> Mathematical Programming Language) is a mathematical programming language and a system for mathematical programming and optimization of linear optimization problems.

The CMPL syntax is similar in formulation to the original mathematical model but also includes syntactic elements from modern programming languages. CMPL is intended to combine the clarity of mathematical models with the flexibility of programming languages.

CMPL executes the COIN-OR OSSolverService, GLPK, Gurobi, SCIP and CPLEX directly to solve the generated model instance. Since it is also possible to transform the mathematical problem into MPS, Free-MPS or OSiL files, alternative solvers can be used.

CMPL is an open source project licensed under GPLv3. It is written in C++ and is available for most of the relevant operating systems (Windows, OS X and Linux).

CMPL is a COIN-OR project initiated by the Technical University of Applied Sciences Wildau and the Institute for Operations Research and Business Management at the Martin Luther University Halle-Wittenberg.

The CMPL distribution contains Coliop which is an IDE (Integrated Development Environment) for CMPL.

Coliop is a project of the Technical University of Applied Sciences Wildau and the Institute for Operations Research and Business Management at the Martin Luther University. Coliop is an open source software licensed under GPLv3. It is written in Java and is as an integral part of the CMPL distribution available for most of the relevant operating systems.
