For example, monomorphic typed Genetic Programming (GP) uses type information to reduce the search space and improve performance. Unfortunately, monomorphic typed GP also loses the generality of untyped GP: the generated programs are only suitable for inputs with the specified type. Polymorphic typed GP improves over monomorphic and untyped GP by allowing the type information to be expressed in a more generic manner, and yet still imposes constraints on the search space. This paper describes a polymorphic GP system which can generate polymorphic programs: programs which take inputs of more than one type and produce outputs of more than one type. date: 1998 date_type: published publisher: Morgan Kaufman oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 41088 lyricists_name: Clack, Christopher lyricists_id: CDCLA00 actors_name: Clack, Christopher actors_id: CDCLA00 actors_role: owner full_text_status: public place_of_pub: San Francisco, CA pagerange: 416-421 event_title: Genetic Programming event_dates: 22 July 1998 - 25 July 1998 institution: Genetic Programming book_title: Genetic Programming 1998: Proceedings of the Third Annual Conference citation: Yu, T; Clack, C; (1998) PolyGP: a polymorphic genetic programming system in Haskell.
