Method Detail

optimize

public String optimize()

Attempt to generate a more readable replacement for the original string. Uses a 1+1 EA to mutate the string with random suffixes generated from the language model. If a mutation yields a greater score according to the model (almost inevitable) AND doesn't result in a reduction in the objective value, the mutated string becomes the new value.
