EF: Evaluation Function to be passed to optim()

In langfob/bdpg: Package For Building and Testing Biodiversity Problem Generators

Evaluation Function to be passed to optim()

Description

Note that the "Local Variable Structures and examples" section below was not labelled as belonging to a function "EF". It was labelled as belonging to a function "fn". I'm assuming that the variables actually belong to EF because "fn" is the argument name that EF gets assigned to when passed to optim().

Usage

EF(
  seed_value,
  tot_num_spp_after_wrapping,
  min_num_spp_on_2_PUs,
  max_max_abundance,
  target_max_abundance_ct,
  add_one_to_abundances,
  outfile,
  mean_sd_pair
)

Arguments

seed_value	integer
tot_num_spp_after_wrapping	integer
min_num_spp_on_2_PUs	integer
max_max_abundance	integer
target_max_abundance_ct	integer
add_one_to_abundances	boolean
outfile	character string
mean_sd_pair	2 element numeric vector containing the mean and standard deviation to use for the lognormal

Value

Returns numeric score from evaluating the given lognormal; the closer to 0 the better
