Nondominated Sorting Scalor

Scalor that returns a the rank of the pareto-front in nondominated sorting as scale. Higher ranks indocate higher fitnesses and therefore "better" individuals.

Configuration Parameters

• epsilon

• nadir

• jitter

• scale_output

• tiebreak

Supported Operand Types

Supported Param classes are: ParamLgl, ParamInt, ParamDbl, ParamFct

Dictionary

This Scalor can be created with the short access form scl() (scls() to get a list), or through the the dictionary dict_scalors in the following way:

# preferred:
scl("nondom")
scls("nondom")  # takes vector IDs, returns list of Scalors

# long form:
dict_scalors$get("nondom")

Examples

so = scl("nondom")
p = ps(x = p_dbl(-5, 5))
# dummy data; note that ScalorNondom does not depend on data content
data = data.frame(x = rep(0, 5))
fitnesses = matrix(c(1, 5, 2, 3, 0, 3, 1, 0, 10, 8), ncol = 2)

so$prime(p)

so$operate(data, fitnesses)
