On Deforesting Parameters of Accumulating Maps
Abstract. Deforestation is a well-known program transformation technique which eliminates intermediate data structures that are passed between functions. One of its weaknesses is t...

Local Temporal Logic is Expressively Complete for Cograph Dependence Alphabets
Abstract. Recently, local logics for Mazurkiewicz traces are of increasing interest. This is mainly due to the fact that the satisfiability problem has the same complexity as in t...

Multi-dimensional Dynamic Knowledge Representation
Abstract. According to Dynamic Logic Programming (DLP), knowledge may be given by a sequence of theories (encoded as logic programs) representing different states of knowledge. Th...

On the Expressibility of Stable Logic Programming
Schlipf (Sch95) proved that Stable Logic Programming (SLP) solves all NP decision problems. We extend Schlipf’s result to prove that SLP solves all search problems in the class ...

Computational Complexity of Some Problems Involving Congruences on Algebras
We prove that several problems concerning congruences on algebras are complete for nondeterministic log-space. These problems are: determining the congruence on a given algebra gen...
