Hi, I try to create a genetic algorithm model and i try to create a fitness function to calculate fitness of every child. However, Matlab gives a function input error.
Here is the code that I wrote so far,
_
function [ fitness ] = calcfitness( breedingpop, nbreeding, penalty )
%UNTITLED Summary of this function goes here
% Detailed explanation goes here
for i=1:nbreeding
fitness = (breedingpop(nbreeding).penalty - breedingpop(i).penalty) / (breedingpop(nbreeding).penalty - breedingpop(1).penaltybreedingpop)
end
i know "penalty" is not the correct way to add as an argument. Does anyone have any idea how I could add penalty as an argument. Thanks

penalty should be a string
childfitness = calcfitness(breedingpop, nbreeding, 'penalty' )
