In this paper we consider updates that are specified as rules and consider simple knowledge bases consisting of ground atoms. We present a translation of the rule based update spe...
ogramming are evaluated along three different guidelines: the programming abstractions the calculus suggests; the underlying programming model; the security mechanisms provided. Th...

Abstract. The first part of the paper gives a brief overview of metaprogramming, in particular program generation, and its use in software development. The second part introduces ...
We develop a calculus for lazy functional programming based on recursion operators associated with data type de nitions. For these operators we derive various algebraic laws that ...
We construct two bijections of the symmetric group Sn onto itself that enable us to show that three new three-variable statistics are equidistributed with classical statistics invo...
