Detailed Description

Recording activities for float variables.

Definition at line 1454 of file float.hh.

Gecode::FloatActivity::FloatActivity ( 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::FloatActivity::FloatActivity ( const FloatActivity & a ) [inline]

Copy constructor.

Definition at line 44 of file activity.hpp.

Gecode::FloatActivity::FloatActivity	(	Home	home,
		const FloatVarArgs &	x,
		double	d = `1.0`,
		FloatBranchMerit	bm = `NULL`
	)

Initialize for float 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.

FloatActivity & Gecode::FloatActivity::operator= ( const FloatActivity & a ) [inline]

Assignment operator.

Definition at line 48 of file activity.hpp.

void Gecode::FloatActivity::init	(	Home	home,
		const FloatVarArgs &	x,
		double	d = `1.0`,
		FloatBranchMerit	bm = `NULL`
	)

Initialize for float 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.
