Abstract. The paper presents a deductive framework for proving program equivalence and its application to automatic verification of transformations performed by optimizing compiler...
In this note we consider the following decision problems. Let be a fixed first-order signature. (i) Given a first-order theory or ground theory T over of Turing degree , a program...
Abstract. Embedded information assurance applications that are critical to national and international infrastructures, must often adhere to certification regimes that require infor...
We present HYPROLOG, a novel integration of Prolog with assumptions and abduction which is implemented in and partly borrows syntax from Constraint Handling Rules (CHR) for integri...
We describe the use of a flexible meta-interpreter for performing access control checks on deductive databases. The meta-program is implemented in Prolog and takes as input a datab...
