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()
|
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.
