Welcome to the Homepages of IPAL, HIPPAL, and LiLi

• IPAL ("Inductive Programming and Learning") is a
  multi-modular A.I. system that combines several
  techniques of symbolic A.I., thereby modeling the
  dynamics of explorative and inductive aspects of
  human cognition.
  IPAL is a joint-venture of the TU Berlin, Department
  of Computer Science and the University of Osnabrueck,
  Intelligent Systems Group.


• HIPPAL is based on a client/server oriented module pattern
  ( -> integration ) and is a Graphical User Interface
  for IPAL. HIPPAL is implemented in Java and thus is
  independent of any specific Operating System.
  HIPPAL is developed by the Intelligent Systems Group,
  University of Osnabrueck


• LiLi is designed to serve as an "operation calculus" or
  (more pragmatically) as a macro language for HIPPAL.
  LiLi is derived from the original McCarthy Lisp and is
  also implemented in Java. Because LiLi is a full featured
  Lisp dialect beneath its role in HIPPAL, it is registered
  as an independent SourceForge project.
