makeMPM2Function: Generator for function with multiple peaks following the multiple peaks model 2.

Description

Generator for function with multiple peaks following the multiple peaks model 2.

Usage

makeMPM2Function(
  n.peaks,
  dimensions,
  topology,
  seed,
  rotated = TRUE,
  peak.shape = "ellipse"
)

Value

[smoof_single_objective_function]

Arguments

n.peaks

[integer(1)]
Desired number of peaks, i. e., number of (local) optima.

dimensions

[integer(1)]
Size of corresponding parameter space.

topology

[character(1)]
Type of topology. Possible values are “random” and “funnel”.

seed

[integer(1)]
Seed for the random numbers generator.

rotated

[logical(1)]
Should the peak shapes be rotated? This parameter is only relevant in case of elliptically shaped peaks.

peak.shape

[character(1)]
Shape of peak(s). Possible values are “ellipse” and “sphere”.

if (require(plot3D)) {
  plot3D(fn)
}
}
if (FALSE) {
fn = makeMPM2Function(n.peaks = 5L, dimensions = 2L,
  topology = "random", seed = 134, rotated = FALSE)
plot(fn, render.levels = TRUE)
