  jenes.chromosome.BitwiseChromosome.BitCoding<java.lang.Integer>
      jenes.chromosome.codings.ShortCoding

public class ShortCoding
extends BitwiseChromosome.BitCoding<java.lang.Integer>

Represents a short coding with 16 bits. There are two possible representations: the two complement ond and the module and sign one. The range representable with the former is [-32768,32767]; the one representable with the latter is [-32767,32767] (the difference is the latter provides two different codes to represent the 0).
