creates a primal heuristic and includes it in SCIP.
- Note
- method has all heuristic callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludeHeurBasic() and setter functions if you seek for a method which is less likely to change in future releases
- 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:
- Parameters

creates a primal heuristic and includes it in SCIP with its most fundamental callbacks. All non-fundamental (or optional) callbacks as, e. g., init and exit callbacks, will be set to NULL.

- Note
- if you want to set all callbacks with a single method call, consider using SCIPincludeHeur() instead
