buildCount.BigBang: Builds the rank and frequency stability counting

Description

Builds the rank and frequency stability counting.

Usage

# S3 method for BigBang
buildCount(o, filter="none", subset=TRUE, maxCounts=o$maxCounts, ...)

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).

maxCounts

Controls the fine-detail in computing the rank in a way that only maxCount ranks are saved despite of the real number solutions. For 1000 solutions and maxCount of 100, the rank is saved every 10 generations. The The default value is 100. Increasing this value increase the amount of memory and time needed to compute the rank stability plot; however, the level of detail in stability is increased.

Value

Nothing.
