Function scip_sys::SCIPisNLPEnabled

pub unsafe extern "C" fn SCIPisNLPEnabled(scip: *mut SCIP) -> c_uint

returns whether the NLP relaxation has been enabled

If the NLP relaxation is enabled, then SCIP will construct the NLP relaxation when the solving process is about to begin. To check whether an NLP is existing, use SCIPisNLPConstructed().

@pre This method can be called if SCIP is in one of the following stages: - \ref SCIP_STAGE_INITPRESOLVE - \ref SCIP_STAGE_PRESOLVING - \ref SCIP_STAGE_EXITPRESOLVE - \ref SCIP_STAGE_PRESOLVED - \ref SCIP_STAGE_INITSOLVE - \ref SCIP_STAGE_SOLVING
