Function Documentation
◆ SCIPreoptnodeGetNVars()
SCIP_EXPORT int SCIPreoptnodeGetNVars | ( | SCIP_REOPTNODE * | reoptnode | ) |
returns the number of bound changes stored in the reoptnode
In debug mode, the following methods are implemented as function calls to ensure type validity. In optimized mode, the methods are implemented as defines to improve performance. However, we want to have them in the library anyways, so we have to undef the defines.returns the number of bound changes stored in the reopttree at ID id
- Parameters
-
reoptnode node of the reopttree
