Detailed Description
template<class F = double>
class EO< F >
EO is a base class for evolvable objects, that is, the subjects of evolution.
EOs have only got a fitness, which at the same time needs to be only an object with the operation less than (<) defined. Fitness says how good is the object; evolution or change of these objects is left to the genetic operators. A fitness less than another means a worse fitness, in whatever the context; thus, fitness is always maximized; although it can be minimized with a proper definition of the < operator. The fitness object must have, besides an void ctor, a copy ctor.

Member Function Documentation
| void EO< F >::fitness | ( | const Fitness & | _fitness | ) | [inline] |
Set fitness.
At the same time, validates it.
- Parameters:
-
_fitness New fitness value.
Reimplemented in PO< eoScalarFitness >.
| bool EO< F >::invalid | ( | ) | const [inline] |
Return true If fitness value is invalid, false otherwise.
- Returns:
- true If fitness is invalid.
Reimplemented in PO< F >, and PO< eoScalarFitness >.
Definition at line 84 of file EO.h.

Returns true if.
- Returns:
- true if the fitness is higher
Definition at line 89 of file EO.h.
Referenced by eoVector< eoScalarFitness, int >::operator<().
| virtual std::string EO< F >::className | ( | void | ) | const [inline, virtual] |
Methods inherited from eoObject.
Return the class id.
- Returns:
- the class name as a std::string
Implements eoObject.
Reimplemented in eoBitParticle< FitT >, eoInt< FitT >, eoRealParticle< FitT >, eoEsFull< Fit >, eoEsSimple< Fit >, eoEsStdev< Fit >, eoReal< FitT >, eoBit< FitT >, eoString< fitnessT >, PO< F >, eoOneMax< FitT >, eoBit< eoScalarFitness >, and PO< eoScalarFitness >.
| virtual void EO< F >::readFrom | ( | std::istream & | _is | ) | [inline, virtual] |
Read object.
\ Calls base class, just in case that one had something to do. The read and print methods should be compatible and have the same format. In principle, format is "plain": they just print a number
- Parameters:
-
_is a std::istream.
- Exceptions:
-
runtime_std::exception If a valid object can't be read.
Implements eoPersistent.
Reimplemented in eoVector< FitT, GeneType >, eoEsFull< Fit >, eoEsSimple< Fit >, eoEsStdev< Fit >, eoBit< FitT >, eoExternalEO< Fit, External >, PO< F >, eoVector< Fit, double >, eoVector< eoScalarFitness, bool >, eoVector< eoScalarFitness, double >, eoVector< eoScalarFitness, int >, eoBit< eoScalarFitness >, and PO< eoScalarFitness >.
Definition at line 108 of file EO.h.
Referenced by eoVector< eoScalarFitness, int >::readFrom(), eoParseTree< FType, Node >::readFrom(), eoOneMax< FitT >::readFrom(), eoExternalEO< Fit, External >::readFrom(), and eoBit< eoScalarFitness >::readFrom().
| virtual void EO< F >::printOn | ( | std::ostream & | _os | ) | const [inline, virtual] |
Write object.
Called printOn since it prints the object _on_ a stream.
- Parameters:
-
_os A std::ostream.
Implements eoPrintable.
Reimplemented in eoVector< FitT, GeneType >, eoVectorParticle< FitT, PositionType, VelocityType >, eoEsFull< Fit >, eoEsSimple< Fit >, eoEsStdev< Fit >, eoBit< FitT >, eoExternalEO< Fit, External >, eoString< fitnessT >, PO< F >, Dummy, Dummy, Dummy, Dummy, eoVector< Fit, double >, eoVector< eoScalarFitness, bool >, eoVector< eoScalarFitness, double >, eoVector< eoScalarFitness, int >, eoVectorParticle< eoScalarFitness, double, double >, eoVectorParticle< eoScalarFitness, bool, double >, eoBit< eoScalarFitness >, and PO< eoScalarFitness >.
