Detailed Description

A base for an integrator. An integrator updates the gauge and momentum fields in the HMC trajectory, approximately conserving the action

Member Function Documentation

◆ action()

virtual double integrator_base::action ( )
inlinevirtual

Return the sum of the action terms at this integrator and all levels below

Reimplemented in gauge_momentum_action< gauge_field >, and action_term_integrator.

Definition at line 87 of file integrator.h.

◆ draw_gaussian_fields()

virtual void integrator_base::draw_gaussian_fields ( )
inlinevirtual

Refresh fields that can be drawn from a gaussian distribution This is needed at the beginning of a trajectory

Reimplemented in gauge_momentum_action< gauge_field >, and action_term_integrator.
