 AGS, like StoGO, is written in C++, but it requires C++11. If the library is built with [C++](NLopt_Installation.md) and compiler supports C++11, AGS will be built too.
 
 AGS is specified within NLopt by `NLOPT_GN_AGS`. Additional parameters of AGS which are not adjustable from the common NLOpt interface are declared and described in `ags.h`. Also an example of solving a constrained problem is given in the AGS source folder.
