HYPERSOLVER: A Graphical Tool for Commonsense Set TheoryMujdatPakkanauthorVarolAkmanauthorThis paper investigates an alternative set theory (due to Peter Aczel) called Hyperset Theory. Aczel uses a graphical representation for sets and thereby allows the representation of non-well-founded sets. A program, called HYPERSOLVER, which can solve systems of equations defined in terms of sets in the universe of this new theory is presented. This may be a useful tool for commonsense reasoning.Artificial IntelligenceSemanticsLogic1995-07Journal (Paginated)
