Genetic Algorithms and Machine Learning for Programmers: IO.get p.68
Hi, minor typo
def fitness_function(chromosome) do
IO.inspect(chromosome)
fit = IO.get("Rate from 1 to 10 ")
String.to_integer(fit)
end
Perhaps, something like,
IO.gets(“Rate from 1 to 10\n”)
|> (&hd(String.split(&1, “\n”))).()
|> String.to_integer()
