SCIPsetHeuristics()

SCIP_EXPORT SCIP_RETCODE SCIPsetHeuristics	(	SCIP *	scip,
		SCIP_PARAMSETTING	paramsetting,
		SCIP_Bool	quiet
	)

sets heuristic parameters values to

• SCIP_PARAMSETTING_DEFAULT which are the default values of all heuristic parameters
• SCIP_PARAMSETTING_FAST such that the time spend for heuristic is decreased
• SCIP_PARAMSETTING_AGGRESSIVE such that the heuristic are called more aggregative
• SCIP_PARAMSETTING_OFF which turn off all heuristics

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.

• SCIP_PARAMSETTING_FAST such that the time spent on heuristics is decreased
• SCIP_PARAMSETTING_AGGRESSIVE such that the heuristics are called more aggressively
• SCIP_PARAMSETTING_OFF which turn off all heuristics

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.

Parameters

scip	SCIP data structure
