Member Function Documentation

§ operator()()

__host__ __device__ __forceinline__ int Sim_Model::demography_sine_wave::operator()	(	const int	population,
		const int	generation
	)		const

Demographic operator, returns population size (individuals), N, for a given population, generation

N = A*sin(pi*(generation-generation_shift) + rho) + D

Definition at line 291 of file template_inline_simulation_functors.cuh.

Member Data Documentation

§ A

float Sim_Model::demography_sine_wave::A

Amplitude of sine wave.

Definition at line 165 of file go_fish.cuh.

§ pi

float Sim_Model::demography_sine_wave::pi

Frequency of sine wave.

Definition at line 166 of file go_fish.cuh.

§ rho

float Sim_Model::demography_sine_wave::rho

Phase of sine wave.

Definition at line 167 of file go_fish.cuh.

§ D

float Sim_Model::demography_sine_wave::D

Offset of sine wave.

Definition at line 168 of file go_fish.cuh.

§ generation_shift

int Sim_Model::demography_sine_wave::generation_shift

number of generations to shift function backwards

useful if you are starting the simulation from a previous simulation state and this function is expecting to start at 0 or any scenario where you want to shift the generation of the function relative to the simulation generation
