Genetic Algorithms in Elixir: Ch6 pp92 order one crossover diagram
The diagram of the generated child is incorrect.
Removing the sliced genes of parent one from the genes of parent two should give a list of “6, 5, 4” that contribute to the new child.
This would give a new child gene of “6, 5, 0, 1, 3, 2, 4”
