We present a framework for encoding planning problems in logic programs with negation as failure, having computational e ciency as our major consideration. In order to accomplish o...
We present a type-based flow analysis for simply typed lambda calculus with booleans, data-structures and recursion. The analysis is exact in the following sense: if the analysis ...
This paper presents an innovative partitionbased time join strategy for temporal databases where time is represented by time intervals. The proposed method maps time intervals to ...
A calculus for developing programs from specifications written as predicates that describe the relationship between the initial and final state is proposed. Such specifications are...
We compare di erent degrees of architecture abstraction and communication reliability in distributed programming languages. A nearly architecture independent logic programming lang...
