Macro Definition Documentation

◆ SCIP_DECL_PARAMCHGD

#define SCIP_DECL_PARAMCHGD ( x ) SCIP_RETCODE x (SCIP* scip, SCIP_PARAM* param)

information method for changes in the parameter

Method is called if the parameter was changed through a SCIPparamsetSetXyz() call (which is called by SCIPsetXyzParam()). It will not be called, if the parameter was changed directly by changing the value in the memory location.

input: scip : SCIP main data structure param : the changed parameter (already set to its new value)

Enumeration Type Documentation

◆ SCIP_ParamType

enum SCIP_ParamType

possible parameter types

Enumerator
SCIP_PARAMTYPE_BOOL	bool values: TRUE or FALSE
SCIP_PARAMTYPE_INT	integer values
SCIP_PARAMTYPE_LONGINT	long integer values
SCIP_PARAMTYPE_REAL	real values

◆ SCIP_ParamSetting

enum SCIP_ParamSetting

possible parameter settings - used to determine the behavior of different SCIP components, e.g., heuristics, separators, ...

Enumerator
SCIP_PARAMSETTING_DEFAULT	use default values
SCIP_PARAMSETTING_AGGRESSIVE	set to aggressive settings
SCIP_PARAMSETTING_FAST	set to fast settings
SCIP_PARAMSETTING_OFF	turn off

Definition at line 48 of file type_paramset.h.
