We present PROB, an animation and model checking tool for the B method. PROB's
animation facilities allow users to gain confidence in their specifications, and unlike the …

We present P ro B, a validation toolset for the B method. P ro B's automated animation
facilities allow users to gain confidence in their specifications. P ro B also contains a model …

The paradigm of Tabled Logic Programming (TLP) is now supported by a number of Prolog
systems, including XSB, YAP Prolog, B-Prolog, Mercury, ALS, and Ciao. The reasons for this …

Software model checking with abstraction refinement is emerging as a practical approach to
verify industrial software systems. Its distinguishing characteristics lie in the way it applies …

Temporal verification of universal (ie, valid for all computation paths) properties of various
kinds of programs, eg, procedural, multi-threaded, or functional, can be reduced to finding …

Non‐monotonic extensions add power to logic programs. However, the main logic
programming language, Prolog, is widely recognized as inadequate to implement these …

Model-based testing has become increasingly popular in recent years. Major reasons
include (1) the need for quality assurance for increasingly complex systems,(2) the emerging …

UML language provides a promising way to overcome software system complexity. In
particular, UML is a unified language that handles different aspects of software modeling …

We present Datalog LITE, a new deductive query language with a linear-time model-
checking algorithm, that is, linear time data complexity and program complexity. Datalog …

This paper presents analysis of nitrate, phosphate and silicate data from the Benguela
upwelling system. Evidence is presented that suggests denitrification occurring close to …
