• Method Detail

  • getBinaryAlphabet

    public static FiniteAlphabet getBinaryAlphabet()

    Gets a Reference to the FlyWeight GA_Binary Alphabet. It contains the Symbols one and zero.

    Returns:

    the finite, flyweight Binary Alphabet

  • one

    public static AtomicSymbol one()

    Returns:

    the GA_Binary symbol "one"

  • createBinary

    public static SymbolList createBinary(String binarySequence)
     throws IllegalSymbolException 

    Creates a SymbolList in the GABinary Alphabet

    Parameters:

    binarySequence - a String like "01010000101010101" with no white space

    Returns:

    a SymbolList parsed from binarySequence

    Throws:

    IllegalSymbolException - if a character other than 1 or 0 is found.

  • zero

    public static AtomicSymbol zero()

    Returns:

    the GA_Binary symbol "zero"

  • uniformMutationDistribution

    public static OrderNDistribution uniformMutationDistribution(FiniteAlphabet a)
     throws IllegalAlphabetException 

    Makes a 1st order distribution which is infact uniform (equivalent to a uniform zero order distribution).

    Parameters:

    a - the zero order Alphabet which will be multiplied into the 1st order alphabet

    Returns:

    the "1st order" distribution

    Throws:

    IllegalAlphabetException - if the Distribution cannot be constructed from a.

  • standardMutationDistribution

    public static OrderNDistribution standardMutationDistribution(FiniteAlphabet a)
     throws IllegalAlphabetException 

    Makes a mutation Distribution where the probability of a Symbol being mutated to itself is zero and the probability of it being changed to any other Symbol in the Alphabet a is 1.0 / (a.size() - 1.0)

    Parameters:

    a - the FiniteAlphabet which mutations are sampled from.

    Returns:

    A Distribution suitable for use in a MutationFunction

    Throws:

    IllegalAlphabetException - if the Distribution cannot be made over the FiniteAlphabet
