Generate optimal design parameters using ant colony optimization

Description

This function can generate a set of optimal design parameters based on given distributions of the rank of optimization target (or budget).

Usage

gen.design.pars(
  dist.mean,
  dist.rank,
  n.of.ants,
  nl,
  q = 1e-04,
  n.of.archive = 100,
  xi = 0.5
)

Arguments

dist.mean	List of means - coordinates
dist.rank	Rank of the archived values of the objective function(s)
n.of.ants	The number of artificial ants in the search.
nl	Neighborhood of the search area
q	The locality of the search (0, 1)
n.of.archive	The number of the solution archive.
xi	The convergence pressure (0, Inf)

Value

Generated optimal design parameter value(s) (i.e., a matrix with n.of.ants rows and n.of.design.pars columns)
