Semantics of sub-probabilistic programs
The aim of this paper is to extend the probabilistic choice in probabilistic programs to sub-probabilistic choice, i.e., of the form (p)P ⋈(q)Q where p + q ⩽ 1. It means that program P is ...

Two-thirds simulation indexes and modal logic characterization
Two-thirds simulation provides a kind of abstract description of an implementation with respect to a specification. In order to characterize the approximate two-thirds simulation, we propose the definition of ...

A verification framework for spatio-temporal consistency language with CCSL as a specification language
The Spatio-Temporal Consistency Language (STeC) is a high-level modeling language that deals natively with spatio-temporal behaviour, i.e., behaviour relating to certain locations and time. Such restriction by...
