Detailed Description

Recording activities for set variables.

Definition at line 1191 of file set.hh.

Constructor & Destructor Documentation

Gecode::SetActivity::SetActivity ( void  )
inline

Construct as not yet initialized.

The only member functions that can be used on a constructed but not yet initialized activity storage is init or the assignment operator.

Definition at line 41 of file activity.hpp.

Gecode::SetActivity::SetActivity ( const SetActivity a)
inline

Copy constructor.

Definition at line 44 of file activity.hpp.

Gecode::SetActivity::SetActivity ( Home  home,
const SetVarArgs x,
double  d = 1.0,
SetBranchMerit  bm = NULL 
)

Initialize for set variables x with decay factor d.

If the branch merit function bm is different from NULL, the activity for each variable is initialized with the merit returned by bm.

Definition at line 42 of file activity.cpp.

Member Function Documentation

SetActivity & Gecode::SetActivity::operator= ( const SetActivity a)
inline

Assignment operator.

Definition at line 48 of file activity.hpp.

void Gecode::SetActivity::init ( Home  home,
const SetVarArgs x,
double  d = 1.0,
SetBranchMerit  bm = NULL 
)

Initialize for set variables x with decay factor d.

If the branch merit function bm is different from NULL, the activity for each variable is initialized with the merit returned by bm.

This member function can only be used once and only if the activity storage has been constructed with the default constructor.

Definition at line 49 of file activity.cpp.
