summary.moead {MOEADr}

summary.moead

Description

S3 method for summarizing moead objects (the output of moead()).

Usage

## S3 method for class 'moead'
summary(
  object,
  ...,
  useArchive = FALSE,
  viol.threshold = 1e-06,
  ndigits = 3,
  ref.point = NULL,
  ref.front = NULL
)

Arguments

object

list object of class moead (generated by moead())

...

other parameters to be passed down to specific summary functions (currently unused)

useArchive

logical flag to use information from object$Archive. Only used if object$Archive is not NULL.

viol.threshold

threshold of tolerated constraint violation, used to determine feasibility of points in object.

ndigits

number of decimal places to use for the ideal and nadir estimates

ref.point

reference point for calculating the dominated hypervolume (only if package emoa is available). If NULL the estimated nadir point is used instead.

ref.front

⁠Np x Nobj⁠ matrix containing a sample of the true Pareto-optimal front, for calculating IGD.

Examples

problem.1 <- list(name = "example_problem",
                  xmin = rep(-1,30),
                  xmax = rep(1,30),
                  m    = 2)
out <- moead(preset    = preset_moead("original2"),
             problem   = problem.1,

                                   maxiter = 100)),
