Liger is an open source integrated optimization environment which is designed to be extensible and have a smooth learning curve so that it can be used by the non-expert in industry. Liger is built about a visual programming language, by which optimization work-flows can be created.
Although there exists a number of optimization frameworks, only commercial and closed source software addresses, to an extent, real-world optimization problems. Typically these packages are low-level libraries which require a large time investment on behalf of the practitioner.
Liger is an open source C++ Integrated Optimization Environment aimed towards ease of use for non-specialists in the use of optimization: The framework is designed to be extensible.
Visualization in Liger is supported by the D3.js library.
Liger is open-source software, and is distributed under LGPLv3.
- The project was initially financially supported by The University of Sheffield and Ford Motor Company Ltd and contributed to the CREO project (funded by the Technology Strategy Board) whose aim was the reduction of CO2 emissions through optimization.
Currently Liger is in active development. Precompiled binaries for Linux, Mac OS and Windows platforms are available here.
