CENSO is a framework for global optimization of nonconvex, possibly spline-constrained, MINLP problems.

• Eigen for linear algebra.
• SPLINTER to compute with splines and other approximations.
• GUROBI for solving LP and MIP problems.
• IPOPT for solving NLP problems.
• BONMIN for solving convex MINLP problems and for heuristically solving non-convex MINLP problems.

• The code examples in the user guide (Docs/UserGuide/manual.pdf) are currently outdated. Refer to the test problems (TestProblems/*) for examples on how to create and solve optimization problems.

If you use CENSO in a scientific work we kindly ask you to cite it. You can cite it as shown in the bibtex entry below (remember to update the date accessed).
