fitness
Calculates the fitness oforg
. This can be done independently of the Population pop (by ignoring the argument in your implementation) or dependent on the other members of thePopulation pop
. Every implementation of this function should assign the fitness value computed in this function to the given organism. This is important so that the organism knows its current fitness. Note that for simple problems this fitness array will contain only one single value. However, to enable multi-objective fitness functions this has to be an array.- Parameters:
org
- TheOrganism
to scorepop
- ThePopulation
to considergenAlg
- the parentGeneticAlgorithm
- Returns:
- the fitness score.
