{"language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"Many biological systems can be modeled as multiaffine hybrid systems. Due to the nonlinearity of multiaffine systems, it is difficult to verify their properties of interest directly. A common strategy to tackle this problem is to construct and analyze a discrete overapproximation of the original system. However, the conservativeness of a discrete abstraction significantly determines the level of confidence we can have in the properties of the original system. In this paper, in order to reduce the conservativeness of a discrete abstraction, we propose a new method based on a sufficient and necessary decision condition for computing discrete transitions between states in the abstract system. We assume the state space partition of a multiaffine system to be based on a set of multivariate polynomials. Hence, a rectangular partition defined in terms of polynomials of the form (xi − c) is just a simple case of multivariate polynomial partition, and the new decision condition applies naturally. We analyze and demonstrate the improvement of our method over the existing methods using some examples."}],"publist_id":"6107","publisher":"Springer","file_date_updated":"2020-07-14T12:44:39Z","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","scopus_import":1,"doi":"10.1007/978-3-319-47151-8_9","citation":{"chicago":"Kong, Hui, Ezio Bartocci, Sergiy Bogomolov, Radu Grosu, Thomas A Henzinger, Yu Jiang, and Christian Schilling. “Discrete Abstraction of Multiaffine Systems,” 9957:128–44.
