Public Member Functions | |
eoPop () | |
Default ctor. | |
eoPop (unsigned _popSize, eoInit< EOT > &_chromInit) | |
Ctor for the initialization of chromosomes. | |
void | append (unsigned _newPopSize, eoInit< EOT > &_chromInit) |
appstd::ends random guys at end of pop. | |
eoPop (std::istream &_is) | |
Ctor from an std::istream; reads the population from a stream, each element should be in different lines. | |
virtual | ~eoPop () |
Empty Dtor. | |
void | sort (void) |
sort the population. | |
void | sort (std::vector< const EOT * > &result) const |
creates a std::vector<EOT*> pointing to the individuals in descending order | |
void | shuffle (void) |
shuffle the population. | |
void | shuffle (std::vector< const EOT * > &result) const |
creates a std::vector<EOT*> pointing to the individuals in random order | |
eoPop< EOT >::iterator | it_best_element () |
returns an iterator to the best individual DOES NOT MOVE ANYBODY | |
const EOT & | best_element () const |
returns an iterator to the best individual DOES NOT MOVE ANYBODY | |
const EOT & | worse_element () const |
returns a const reference to the worse individual DOES NOT MOVE ANYBODY | |
eoPop< EOT >::iterator | it_worse_element () |
returns an iterator to the worse individual DOES NOT MOVE ANYBODY | |
eoPop< EOT >::iterator | nth_element (int nth) |
slightly faster algorithm than sort to find all individuals that are better than the nth individual. | |
Fitness | nth_element_fitness (int which) const |
returns the fitness of the nth element | |
void | nth_element (int which, std::vector< const EOT * > &result) const |
const nth_element function, returns pointers to sorted individuals up the the nth | |
void | swap (eoPop< EOT > &other) |
does STL swap with other pop | |
virtual void | sortedPrintOn (std::ostream &_os) const |
Prints sorted pop but does NOT modify it! | |
virtual void | printOn (std::ostream &_os) const |
Write object. | |

We have no idea if a population can be some other thing that a std::vector, but if somebody thinks of it, this concrete implementation can be moved to "generic" and an abstract Population interface be provided.
The template can be instantiated with anything that accepts a "size" and eoInit derived object. in the ctor. EOT must also have a copy ctor, since temporaries are created and then passed to the eoInit object

sort the population.
Use this member to sort in order of descending Fitness, so the first individual is the best!

virtual void eoPop< EOT >::printOn | ( | std::ostream & | _os | ) | const [inline, virtual] |
Write object.
It's called printOn since it prints the object _on_ a stream.
_os | A std::ostream. |
Implements eoPrintable.
Read object.
The EOT class must have a ctor from a stream;
_is | A std::istream. |
Implements eoPersistent.
