Function SCIPsetRelaxSolVal

pub unsafe extern "C" fn SCIPsetRelaxSolVal(
    scip: *mut SCIP,
    relax: *mut SCIP_RELAX,
    var: *mut SCIP_VAR,
    val: f64,
) -> SCIP_RETCODE

sets the value of the given variable in the global relaxation solution; this solution can be filled by the relaxation handlers and can be used by heuristics and for separation; You can use SCIPclearRelaxSolVals() to set all values to zero, initially; after setting all solution values, you have to call SCIPmarkRelaxSolValid() to inform SCIP that the stored solution is valid

@return \ref SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See \ref SCIP_Retcode “SCIP_RETCODE” for a complete list of error codes.

@pre This method can be called if @p scip is in one of the following stages: - \ref SCIP_STAGE_PRESOLVED - \ref SCIP_STAGE_SOLVING

@note This method incrementally updates the objective value of the relaxation solution. If the whole solution should be updated, using SCIPsetRelaxSolVals() instead or calling SCIPclearRelaxSolVals() before setting the first value to reset the solution and the objective value to 0 may help the numerics.
