Description

Computes the “mean” fitness from several solutions.

Usage

1
2
## S3 method for class 'BigBang'
meanFitness(o, filter="none", subset=TRUE, ...)

Arguments

filter

The BigBang object can save information about solutions that did not reach the goalFitness. filter=="solutions" ensures that only chromosomes that reach the goalFitness are considered. fitlter=="none" take all chromosomes. filter=="nosolutions" consider only no-solutions (for comparative purposes).

subset

Second level of filter. subset can be a vector specifying which filtered chromosomes are used. It can be a logical vector or a numeric vector (indexes in order given by $bestChromosomes in BigBang object variable). If it is a numeric vector length one, a positive value means take those top chromosomes sorted by fitness, a negative value take those at bottom.

Details

The mean is built considering all solutions. For solutions that have finished earlier, the final fitness is used for futher genertions.

Value

A vector with the mean fitness in each generation.
