Table 3 Overview of the approximations
AbbreviationGeneral approach
MaxEntStationary microscopic distribution derived from macroscopic observables.
DynMaxEntAny approximation for the dynamics of observables based on a combination of MaxEnt variational ansatz, quasi-stationarity assumption, and a dynamical (e.g., diffusion) equation for the probability distribution.
AbbreviationMethod in quantitative genetics
Continuous DynMaxEntRefers to the method of Barton and de Vladar (2009), where the dynamics are captured by diffusion equation (1).
General DynMaxEntThe approximation introduced here, which generalizes the continuous DynMaxEnt method. This new approximation distinguishes between the bulk mass that behaves as in the continuous problem and the coupled boundary masses that behave as discrete quantities.
