Veröffentlicht: von & gespeichert unter General

                We are glad to inform you that SACOBRA package is now available on CRAN.  SACOBRA package performs surrogate-assisted optimization by utilizing radial basis function interpolation. SACOBRA solver is a derivative-free optimizer appropriate to address constrained expensive optimization problems.

A New Repair Method For Constrained Optimization

Veröffentlicht: von & gespeichert unter Conference/Journal paper, General, MONREP, Publications, Research Projects

Many real-world optimization problems are dealing with constraints. The valid solution for constrained optimization problems (COP) lies somewhere in the feasible region which is a sub-set of the input-space. The borders of the feasible area are defined by one or many constraints. Existance of constraints makes the optimization problems more demanding. There are different approaches to... Mehr »
