Genetic Algorithms in Elixir: text/population size incorrect (page 159)

There is a small error on page 159.

The text says:

[…] you’ll decrease the population size to 5

But the code shows the population size being decreased to 2.

      tiger =
        Genetic.run(TigerSimulation,
          population_size: 2,
          selecion_rate: 1.0,
          mutation_rate: 0.0,
          statistics: %{average_tiger: &TigerSimulation.average_tiger/1}
        )

Also there’s a typo on the next page.

{:gnuplut, "~> 1.19"}

should be:

{:gnuplot, "~> 1.19"}
