◆ SCIPvarIsRelaxationOnly()
returns whether a variable has been introduced to define a relaxation

Also conflicts with relaxation-only variables are not generated at the moment. Relaxation-only variables do not appear in the objective.

creates and captures problem variable; if variable is of integral type, fractional bounds are automatically rounded; an integer variable with bounds zero and one is automatically converted into a binary variable;
- Warning
- When doing column generation and the original problem is a maximization problem, notice that SCIP will transform the problem into a minimization problem by multiplying the objective function by -1. Thus, the original objective function value of variables created during the solving process has to be multiplied by -1, too.
- Returns
- SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.
- Precondition
- This method can be called if
scipis in one of the following stages:
- Note
- the variable gets captured, hence at one point you have to release it using the method SCIPreleaseVar()
- Parameters
