The Combinatorial Object Server++
Welcome! On this website you can- generate combinatorial objects with parameters of your choice
- explore various combinatorial algorithms
- download free source code for those algorithms (GNU General Public License)
The Combinatorial Object Server was first launched by Frank Ruskey at the University of Victoria (Canada). The original website has been shut down for some time, and this new version has been relaunched in 2018 by Torsten Mütze, Joe Sawada and Aaron Williams. We plan to bring the original Combinatorial Object Server content back online step by step, and to extend it by new material. This website also provides an experimental interface to many of the combinatorial algorithms that are part of the FXT library written in C++ by Jörg Arndt.
This website is intended as a community project, and welcomes your contributions and feedback (new algorithms/code/references)! All code is available via the public GIT repository https://gitlab.com/tmuetze81/cos. Please also let us know when you find the material on this website useful for your research.
