Total of weight must be greater than zero

Error: def nextGeneration(population, fitness):

min_fitness = min(fitness)
if min_fitness < 0 :
    fitness = [min_fitness + f for f in fitness]

Reson: when min_fitness too big (-10202), all f < 0 so total < 0 f + min_fitness < 0 To fix: f + -min_fitness > 0 fitness = [-min_fitness + f for f in fitness]
