Source

    var: *mut SCIP_VAR,
    fixedval: f64,
) -> SCIP_RETCODE
Expand description

injects a change of variable’s bounds into current probing node to fix the variable to the specified value; the same can also be achieved with a call to SCIPfixVar(), but in this case, the bound changes would be treated like deductions instead of branching decisions

@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_PRESOLVING - \ref SCIP_STAGE_SOLVING
