First there is an error in my code :(
These are the allowed symbols from which the creator function can
choose to create or mutate a gen:
def allowed-symbols (str "abcdefghijklmnopqrstuvwxyzäöü"
"ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÜ"))
This is the targetd which should be fulfilled:
(def the_target "Thursday Next")
The first error is, that in the allowed symbols the Space (' ') is
missing. So without this symbol/character the algorithm has no chance
to finish.
The correct definition for the symbols are (with the missing space):
def allowed-symbols (str "abcdefghijklmnopqrstuvwxyzäöü "
"ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÜ "))
So the algorithm tries to design the String "Thursday Next" by
exploring many possible variations and to get as near as possible to
the solution "Thursday Next".
The main purpose of this algorithm, I think, is to show how you can
use agents and atoms to implement a genetic algorithm.
