Detailed Description

template<typename T>
class Chromosome< T >

The super class for different type of chromosomes.

Parameters:

T

Type T can be bool (binary problems), int (combinatorial problems) or real (continuous problems).

See also:

Chromosome_Binary | Chromosome_Real

Constructor & Destructor Documentation

template<typename T>

Chromosome< T >::Chromosome

(

)

[inline]

Default constructor.

Create an instance of chromosome of type T.

template<typename T>

Chromosome< T >::Chromosome

(

const vector< T > &

v

)

[inline]

Constructor.

Parameters:

v

Input vector

Create the chromosome from a vector of type T.

Remarks:

Actually a copy constructor.

template<typename T>

Chromosome< T >::Chromosome	(	const size_t	size,
		vector< double >	lowerBounds,
		vector< double >	upperBounds
	)			[inline]

Constructor.

Parameters:

	size	Chromosome size, normally equal to the number of optimization variables.
	lowerBounds	Vector of lower bound values.
	upperBounds	Vector of upper bound values.

Create the chromosome of given size and bounds.

template<typename T>

Chromosome< T >::Chromosome	(	vector< double >	phenotype,
		vector< double >	lowerBounds,
		vector< double >	upperBounds
	)			[inline]

Constructor.

Parameters:

	phenotype	Input phenotype.
	lowerBounds	Vector of lower bound values.
	upperBounds	Vector of upper bound values.

Generate the chromosome from a vector of doubles.

Remarks:

Same as Chromosome<T>::fromDoubleVector(v).

See also:

Chromosome<T>::fromDoubleVector

Member Function Documentation

template<typename T>

virtual void Chromosome< T >::fromDoubleVector

(

vector< double > &

phenotype

)

[inline, virtual]

Encode function.

Parameters:

phenotype

Phenotype (optimization variables).

Exceptions:

<exception

class> Description of criteria for throwing this exception.

Encode a phennotype to its genotype representation

Remarks:

Write remarks for fromDoubleVector here.

See also:

toDoubleVector()

Reimplemented in Chromosome_Binary, and Chromosome_Real.

template<typename T>

virtual vector<double> Chromosome< T >::toDoubleVector

(

)

[inline, virtual]

Decode function.

Returns:

The decoded vector of doubles.

Decode a genotype to a double vector

See also:

fromDoubleVector()

Reimplemented in Chromosome_Binary, and Chromosome_Real.

template<typename T>

virtual Chromosome* Chromosome< T >::clone

(

)

[inline, virtual]

Clone function.

Returns:

A "twin" of the current chromosome

Reimplemented in Chromosome_Binary, and Chromosome_Real.

template<typename T>

bool Chromosome< T >::operator<

(

Chromosome< T > &

chromosome

)

[inline]

Compare 2 chromosome.

Parameters:

chromosome

The chromosome to compare.

Returns:

True if the current chromosome has lower fitness value, false otherwise.

Compare the fitness value with another chromosome.

template<typename T>

string Chromosome< T >::toString

(

)

[inline, virtual]

Convert the chromosome to string.

Returns:

The string representing the chromosome.

Convert the chromosome to string.

Remarks:

To be inherited by different chromosome classes. E.g.: we want a concatenated binary strings, but a space-delimited or comma-delimited double string, i.e., 0100110010010 vs. {1.2, 0.3, 5.9}

template<typename T>

bool Chromosome< T >::isInBound

(

)

[inline]

Bound checking.

Returns:

True if all the variables is inbound, false otherwise.

Check if the chromsome is within the given bounds.

Remarks:

Used in many local search / constrained optimization problem
