)

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

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_PARAMTYPE_CHAR	characters
SCIP_PARAMTYPE_STRING	strings: arrays of characters

Definition at line 36 of file type_paramset.h.

enum SCIP_ParamSetting

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

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.

enum SCIP_ParamEmphasis

possible parameter emphases - used to determine the general SCIP behavior

Enumerator:

SCIP_PARAMEMPHASIS_DEFAULT	use default values
SCIP_PARAMEMPHASIS_CPSOLVER	get CP like search (e.g. no LP relaxation)
SCIP_PARAMEMPHASIS_EASYCIP	solve easy problems fast
SCIP_PARAMEMPHASIS_FEASIBILITY	detect feasibility fast
SCIP_PARAMEMPHASIS_HARDLP	be capable to handle hard LPs
SCIP_PARAMEMPHASIS_OPTIMALITY	prove optimality fast
SCIP_PARAMEMPHASIS_COUNTER	get a feasible and "fast" counting process
