A method to perform nonmonotonic relational rule computations is presented, called the split technique, The goal is to avoid redundant computations with rules that can insert and delete sets of tuples speciied by the rule body. The method is independent of the control strategy that governs rule ring. Updatable relations are partitioned, as the computation progresses, into blocks of tuples such ...

Abstract This paper considers the Omega function, proposed by Cascon, Keating & Shadwick, as a performance evaluation measure for comparison between financial assets. We discuss the optimization problems which arise when the Omega function is used as a basis for portfolio selection. We show that the problem of choosing invested fractions to maximize Omega typically has many local solutions and ...

This paper develops optimal gender assignment theory, an approach to gender assignment couched within the formalism of Optimality Theory [Prince, Alan, Smolensky, Paul, 1993. Optimality Theory: Constraint Interaction inGenerative Grammar. Rutgers University andUniversity of Colorado, Boulder] and drawing on Steinmetz’ [Steinmetz, Donald, 1985. Gender in German and Icelandic: inanimate nouns. In...
