Usually set to TRUE. local is constraint only valid locally? Usually set to FALSE. Has to be set to TRUE, e.g., for branching constraints. modifiable is constraint modifiable (subject to column generation)? Usually set to FALSE. In column generation applications, set to TRUE if pricing adds coefficients to this constraint. dynamic is constraint subject to aging? Usually set to FALSE. Set to TRUE for own cuts which are separated as constraints. removable should the relaxation be removed from the LP due to aging or cleanup? Usually set to FALSE. Set to TRUE for 'lazy constraints' and 'user cuts'. stickingatnode should the constraint always be kept at the node where it was added, even if it may be moved to a more global node? Usually set to FALSE.

Set to TRUE for own cuts which are separated as constraints. removable should the relaxation be removed from the LP due to aging or cleanup? Usually set to FALSE. Set to TRUE for 'lazy constraints' and 'user cuts'. stickingatnode should the constraint always be kept at the node where it was added, even if it may be moved to a more global node? Usually set to FALSE. Set to TRUE to for constraints that represent node data. success pointer store if the paring process was successful

method to collect the variables of a constraint
If the number of variables is greater than the available slots in the variable array, nothing happens except that the success point is set to FALSE. With the method SCIPconsGetNVars() it is possible to get the number of variables a constraint has in its scope.
- Note
- The success pointer indicates if all variables were copied into the vars arrray.
- It might be that a constraint handler does not support this functionality, in that case the success pointer is set to FALSE.
- Parameters
