Problem Addressed
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:
“The problem of the novelist who wishes to write about a man’s encounter with God is how he shall make the experience—which is both natural and supernatural—understandable, and credible, to his reader. In any age this would be a problem, but in our own, it is a well- nigh insurmountable one. Today’s audience is one in which religious feeling has become, if not atrophied, at least vaporous and sentimental.”
—Flannery O’Connor (1925–1964)
“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)
