BinaryReal

public BinaryReal(int numberOfBits,
                  double lowerBound,
                  double upperBound)

Constructor

Parameters:

numberOfBits - Length of the binary string.

lowerBound - The lower limit for the encodings.variable

upperBound - The upper limit for the encodings.variable.

BinaryReal

public BinaryReal(java.util.BitSet bits,
                  int nbBits,
                  double lowerBound,
                  double upperBound)

Parameters:

bits - BitSet

nbBits - Number of bits

Overrides:

setValue in class Variable

Throws:

JMException
