摘要: A parallel program often defines a relation not function. The constrains the output to lie in some R input, but particular produced during computation can depend on time behaviour of component processes. This suggests use relational language as an applicative for programming.The Horn clause subset predicate logic is with established procedural interpretation non-deterministic sequential computations [Kowalski 1974]. In this paper we modify and extend that define special purpose evaluator.
