Detailed Description

EvoParam - class that represents a parameter that is modifiable (optimizable) by evolutionary algorithms.

Constructor & Destructor Documentation

EvoParam()

grail::evolution::EvoParam::EvoParam ( size_t  domainLength )

protected

EvoParam - Constructor.

Parameters

domainLength

- the number of distinct values EvoParam may take.

Member Function Documentation

Randomize()

void grail::evolution::EvoParam::Randomize

(

std::mt19937_64 &

rand_gen

)

Sets to a random possible value from a domain.

Parameters

rand_gen

- random number generator.

SetPositionIndex()

void grail::evolution::EvoParam::SetPositionIndex

(

size_t

position

)

Sets the position of the parameter i.e. the index of the currently assigned element from the domain.

Parameters

position

- the number >= 0 and < domainLength.

ToString()

std::string grail::evolution::EvoParam::ToString ( ) const

virtual

ToString - returns the string representation of the current value hold by the parameter.

Reimplemented in grail::evolution::TypedEvoParam< T >.

Member Data Documentation

positionIndex

size_t grail::evolution::EvoParam::positionIndex

protected

positionIndex - EvoParam uses positionIndex to point to an element from its domain.
