Genetic Algorithms in Elixir: Possible typo in uniform reinsertion code (page 134)

Should this section of text on page 134:

Finally, test your problem with uniform reinsertion. To do this, take the same
approach you took with elitist reinsertion:

soln = Genetic.run(Schedule,
                   reinserton_strategy:
                     &Toolbox.Reinsertion.elitist(&1, &2, &3, 0.1),
                   selection_rate: 0.8,
                   mutation_rate: 0.1)
IO.write("\n")
IO.inspect(soln)

be this instead:

Finally, test your problem with uniform reinsertion. To do this, take the same
approach you took with elitist reinsertion:

soln = Genetic.run(Schedule,
                   reinserton_strategy:
                     &Toolbox.Reinsertion.uniform(&1, &2, &3, 0.1),
                   selection_rate: 0.8,
                   mutation_rate: 0.1)
IO.write("\n")
IO.inspect(soln)

The elitist call being replaced by the uniform?
