pub unsafe extern "C" fn SCIPvarIsRelaxationOnly(
var: *mut SCIP_VAR,
) -> c_uintExpand description
returns whether a variable has been introduced to define a relaxation
These variables are only valid for the current SCIP solve round, they are not contained in any (checked) constraints, but may be used in cutting planes, for example. Relaxation-only variables are not copied by SCIPcopyVars and cuts that contain these variables are not added as linear constraints when restarting or transferring information from a copied SCIP to a SCIP. Also conflicts with relaxation-only variables are not generated at the moment. Relaxation-only variables do not appear in the objective.
