Genetic Algorithms in Elixir: Possible typo in repair_helper function (page 104)
@seanmor5
In the repair_helper function on page 104 the following line:
if MapSet.size(chromosome) >= k do
should be:
if MapSet.size(chromosome.genes) >= k do
as previously the Chromosome Type was defined as a struct and MapSet.size/1 expects a Enum?
