makeMPM2Function function

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

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

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 .

Returns

[smoof_single_objective_function]

Examples

## Not run:

fn = makeMPM2Function(n.peaks = 10L, dimensions = 2L,
  topology = "funnel", seed = 123, rotated = TRUE, peak.shape = "ellipse")
if (require(plot3D)) {
  plot3D(fn)
}
## End(Not run)

## Not run:

fn = makeMPM2Function(n.peaks = 5L, dimensions = 2L,
  topology = "random", seed = 134, rotated = FALSE)
plot(fn, render.levels = TRUE)
## End(Not run)
