We investigate the problem of producing symmetric tilings by programs in a uniform way. By this, we mean that the construction of a tiling should be parameterized by the geometric...
Abstract. This paper proposes a diagnosis algorithm for locating a certain kind of errors in logic programs: variable binding errors that result act symptoms during compile-time ch...
Abstract. We extend the algebraic approach of Meseguer and Montanari from ordinary place/transition Petri nets to contextual nets, covering both the collective and the individual t...
: This paper presents database programming language constructs that. can be used to realize a variety of different semantics for rule application in active database syst.ems. The p...
This paper describes the implementation of a purely functional programming language for building software systems. In this language, external tools like compilers and linkers are ...
