Abstract
Kocabas (1991) describes a situation from particle physics in which
quantum properties and conservation laws are postulated from lists of
observed and unobserved reactions. Kocabas also presents a program
named BR-3 that can rediscover some accepted quantum properties from
textbook data, although it fails on a more difficult example from the
same source. This paper describes PAULI, a program that solves the
same task as BR-3 but uses a different problem-solving model. PAULI
produces different, simpler solutions than does BR-3, and it can also
handle the problematic example. After comparing the two programs, we
conclude that PAULI offers distinct advantages over its predecessor,
which we attribute to an algebraic approach to reasoning about sets of
reactions.
