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 scip is in one of the following stages:
Note
the variable gets captured, hence at one point you have to release it using the method SCIPreleaseVar()

◆ SCIPwriteVarsList()

SCIP_RETCODE SCIPwriteVarsList ( SCIP scip,
FILE *  file,
SCIP_VAR **  vars,
int  nvars,
SCIP_Bool  type,
char  delimiter 
)

print the given list of variables to output stream separated by the given delimiter character;

i. e. the variables x1, x2, ..., xn with given delimiter ',' are written as: <x1>, <x2>, ..., <xn>;

the method SCIPparseVarsList() can parse such a string

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 scip is in one of the following stages:
Note
The printing process is done via the message handler system.
Parameters
scipSCIP data structure
fileoutput file, or NULL for stdout
varsvariable array to output
nvarsnumber of variables
typeshould the variable type be also posted
delimitercharacter which is used for delimitation
