gen.design.pars: 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
)

Value

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

Arguments

dist.mean

List of means - coordinates

dist.rank

Rank of the archived values of objective function

n.of.ants

Number of ants used in each iteration after the initialization of power analysis for calculating required budget, default value is 10.

nl

Neighborhood of the search area

q

Locality of the search (0,1), default is 0.0001.

n.of.archive

Size of the solution archive, default is 100.

xi

Convergence pressure (0, Inf), suggested: (0, 1), default is 0.5.
