We present the background and justi cation for a new approachto studying computation and computational complexity. We focus on categories of problems and categories of solutions w...
An estimation algorithm for a query is a probabilistic algorithm that computes an approximation for the size (number of tuples) of the query. One class of estimation algorithms us...
Abstract. Algebraic compilers provide a powerful and convenient mechanism for specifying language translators. With each source language operation one associates a computation for ...
The aim of this paper is to show a method that is able to detect a particular class of semantic inconsistencies in a rule-based system (RBS). A semantic inconsistency is defined by...
The goal of research in programming languages should be to develop languages that integrates the best of concepts and constructs from the various programming paradigms. We do not a...
