.. _method-approximate_control_variate-acv_multifidelity: """"""""""""""""" acv_multifidelity """"""""""""""""" Approximate control variate (ACV) algorithm that mimics MFMC by employing a nested pyramid sample pattern This ACV variant uses sample set definitions that are similar to multifidelity Monte Carlo (MFMC), in that sample sets are nested with each new level adding an increment on top of the previous. .. toctree:: :hidden: :maxdepth: 1 **Specification** - *Alias:* acv_mf - *Arguments:* None **Description** **Theory** Refer to :cite:p:`GORODETSKY2020109257` for a helpful sample set diagram.
