CEM is a novel approach to the form-finding of mixed tension-compression spatial structure in static equilibrium. The CEM is developed by Patrick Ole Ohlbrock and Pierluigi D'Acunto at the Chair of Structural Design at the ETH Zurich (http://www.schwartz.arch.ethz.ch/).
The CEM library makes use of a .NET wrapper (https://github.com/BrannonKing/NLoptNet/ - MIT license) of the NLOpt C library for nonlinear optimization (https://nlopt.readthedocs.io/en/latest/ - LGPL license).
If you use the CEM library, please refer to the official GitHub repository:
