In type-free conventional, Koza-style GP, the function set must meet the requirement of closure: all functions must be capable of accepting as their arguments the output of all other functions in the function set. Usually, this is implemented by dealing with a single data-type such as double-precision floating point. Whilst modern Genetic Programming frameworks supporting typing, such type-systems have limitations that Grammatical Evolution does not suffer from.

Famous quotes containing the words problem and/or addressed:
“Only in the problem play is there any real drama, because drama is no mere setting up of the camera to nature: it is the presentation in parable of the conflict between Man’s will and his environment: in a word, of problem.”
—George Bernard Shaw (1856–1950)
“Must! Is must a word to be addressed to princes? Little man, little man! thy father, if he had been alive, durst not have used that word.”
—Elizabeth I (1533–1603)
