In this paper, we present a method and a tool to build symbolic labelled transition systems from B specifications. The tool, called GeneSyst, can take into account refinement levels and can visualize the decomposition of abstract states in concrete hierarchical states. The resulting symbolic transition system represents all the behaviors of the initial B(More)
This paper gives a brief description of the recent improvements of lpg, a programming language that integrates algebraic and logic programming paradigms. In this language, functions are deened by means of constructor-based conditional term rewriting systems and predicates are deened by means of Horn clauses where the bodies may contain classical literals as(More)
Rising atmospheric [CO2 ], ca , is expected to affect stomatal regulation of leaf gas-exchange of woody plants, thus influencing energy fluxes as well as carbon (C), water, and nutrient cycling of forests. Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO2 ], ci ,(More)
This paper presents the results of the RNTL BOM project, which aimed to develop an approach to generate efficient code from B formal developments. The target domain is smart card applications, in which memory and code size is an important factor. The results detailed in this paper are a new architecture of the translation process, a way to adapt the B0(More)
