Genetic Algorithms in Elixir: Typo in the name of function being modified (page 77)
@seanmor5
On page 77, the following text:
“Change run to look like this:”
should be “Change evolve to look like this”
and lower on the page the text:
“Here you adjust run to account for select returning…”
should be “Here you adjust evolve to account for select returning…”
since the function in between those two excerpts is the evolve function.
