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:

◆ SCIPincludeHeurBasic() SCIP_RETCODE SCIPincludeHeurBasic ( SCIP * scip, SCIP_HEUR ** heur, const char * name, const char * desc, char dispchar, int priority, int freq, int freqofs, int maxdepth, SCIP_HEURTIMING timingmask, SCIP_Bool usessubscip, SCIP_DECL_HEUREXEC((*heurexec)) , SCIP_HEURDATA * heurdata )

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. Optional callbacks can be set via specific setter functions, see SCIPsetHeurCopy(), SCIPsetHeurFree(), SCIPsetHeurInit(), SCIPsetHeurExit(), SCIPsetHeurInitsol(), and SCIPsetHeurExitsol()

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