MAX_WEIGHT
final public static double MAX_WEIGHT(Code)




Constructor Detail
CoinsEnergyFitnessFunction
public CoinsEnergyFitnessFunction(int a_targetAmount, double a_maxWeight)(Code)




Method Detail
amountOfChange
public static int amountOfChange(IChromosome a_potentialSolution)(Code)
Calculates the total amount of change (in cents) represented by the given potential solution and returns that amount.
Parameters:
  a_potentialSolution - the potential solution to evaluate the total amount of change (in cents) represented by thegiven solution
author:
   Neil Rotstan
since:
   1.0



changeDifferenceBonus
protected double changeDifferenceBonus(double a_maxFitness, int a_changeDifference)(Code)
Bonus calculation of fitness value.
Parameters:
  a_maxFitness - maximum fitness value appliable
Parameters:
  a_changeDifference - change difference in coins for the coins problem bonus for given change difference
author:
   Klaus Meffert
since:
   2.3



computeCoinNumberPenalty
protected double computeCoinNumberPenalty(double a_maxFitness, int a_coins)(Code)
Calculates the penalty to apply to the fitness value based on the ammount of coins in the solution
Parameters:
  a_maxFitness - maximum fitness value allowed
Parameters:
  a_coins - number of coins in the solution penalty for the fitness value base on the number of coins
author:
   John Serri
since:
   2.4
