Detailed Description

functor: models selection coefficient as linearly dependent on frequency

(slope < 0) := balancing selection model (negative frequency-dependent selection)
(slope = 0) := constant selection
(slope > 0) := reinforcement selection model (positive frequency-dependent selection)

§ selection_linear_frequency_dependent() [3/3]

template<typename Functor_demography , typename Functor_inbreeding >
Sim_Model::selection_linear_frequency_dependent::selection_linear_frequency_dependent ( float  gamma_slope,
float  gamma_intercept,
Functor_demography  demography,
Functor_inbreeding  F,
int  forward_generation_shift = 0 
)
inline

constructor: effective selection

slope = gamma_slope/(2*demography(0,forward_generation_shift)/(1+F(0,forward_generation_shift)))
intercept = gamma_intercept/(2*demography(0,forward_generation_shift)/(1+F(0,forward_generation_shift)))

Parameters
forward_generation_shift(optional input) default 0
allows you to push the population size and inbreeding coefficient value to the state forward in time - useful if you are starting the simulation from a previous simulation state and are using the same functions as the previous simulation or any time you want to shift the generation of the demography and inbreeding functions from 0
