action_base Class Reference

#include <integrator.h>

Inheritance diagram for action_base:

Public Member Functions
virtual double	action ()
	Calculate and return the action.
virtual void	backup_fields ()
	Make a copy of fields updated in a trajectory.
virtual void	draw_gaussian_fields ()
virtual void	force_step (double eps)
virtual void	restore_backup ()
	Restore the previous backup.

Detailed Description

Define the standard action term class. Action terms are used in the HMC algorithm and implement calculating the action itself and updating the underlying fields
