ForwardSimulate: Forward simulate given the optimal havesting policy, D

In cboettig/pdg_control: Pretty Darn Good Control

Description

Forward simulate given the optimal havesting policy, D

Usage

ForwardSimulate(f, pars, x_grid, h_grid, x0, D, z_g, z_m = function(x) 1,
  z_i = function(x) 1, profit = NULL, OptTime = NULL)

Arguments

f	the growth function of the escapement population (x-h) should be a function of f(y, p), with parameters p
x_grid	the discrete values allowed for the population size, x
h_grid	the discrete values of harvest levels to optimize over
D	the optimal solution indices on h_grid, given for each possible state at each timestep
z_g	a function which returns a random multiple for population growth
z_m	a function which returns the measurement uncertainty in the assessment of stock size
z_i	a function which returns a random number from a distribution for the implementation uncertainty in quotas
profit	function, if known
p	the parameters of the growth function
Xo	initial stock size

Value

a data frame with the time, fishstock, harvested amount, and what the escapement ("unharvested").
