dict_scalors_one: Single Dimension Scalor

In miesmuschel: Mixed Integer Evolution Strategies

Single Dimension Scalor

Description

Scalor that returns a the fitness value of a single objective dimension as scale.

Configuration Parameters

• objective :: integer(1)
  objective to return as scale, ranges from 1 (the default, first objective) to the number of objectives of the function being optimized.

Supported Operand Types

Supported Domain classes are: p_lgl ('ParamLgl'), p_int ('ParamInt'), p_dbl ('ParamDbl'), p_fct ('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("one")
scls("one")  # takes vector IDs, returns list of Scalors

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

# dummy data; note that ScalorOne 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)

so$param_set$values$objective = 2

so$operate(data, fitnesses)
