approximateRefPoints function

Helper function to estimate reference points.

E.g., for calculation of dominated hypervolume.

approximateRefPoints(df, obj.cols = c("f1", "f2"), offset = 0, as.df = FALSE)

Arguments

• df: [data.frame]

  Data frame with the required structure, i.e. the data frame must contain a problem column "prob" as well as objective column(s).

• obj.cols: [character(>= 2)]

  Column names of the objective functions. Default is c("f1", "f2"), i.e., the bi-objective case is assumed.

• offset: [numeric(1)]

  Offset added to reference points. Default is 0.

• as.df: [logical(1)]

  Should a data.frame be returned? Default is FALSE. In this case a named list is returned.

Returns

[list | data.frame]
