Genetic Algorithms in Elixir: mismatch between order_one function naming (page 92, 94)

@seanmor5

On page 92: the order_one crossover type is declared as

def order_one_crossover(p1, p2) do

On page 94: The default is set to

&Toolbox.Crossover.order_one/2

Marked As Solved

Thanks! It should be order_one_crossover to match the rest of the implementations. I believe there may be some additional bad references to single_point versus single_point_crossover as well. I’ll put fix this for the next version as well!
