QUASY: Quantitative Synthesis Tool
نویسندگان
چکیده
We present the tool QUASY, a quantitative synthesis tool. QUASY takes qualitative and quantitative specifications and automatically constructs a system that satisfies the qualitative specification and optimizes the quantitative specification, if such a system exists. The user can choose between a system that satisfies and optimizes the specifications (a) under all possible environment behaviors or (b) under the most-likely environment behaviors given as a probability distribution on the possible input sequences. QUASY solves these two quantitative synthesis problems by reduction to instances of 2-player games and Markov Decision Processes (MDPs) with quantitative winning objectives. QUASY can also be seen as a game solver for quantitative games. Most notable, it can solve lexicographic mean-payoff games with 2 players, MDPs with meanpayoff objectives, and ergodic MDPs with mean-payoff parity objectives.

متن کاملQuantitative Evaluation of Behavioral Synthesis Approaches for Reconfigurable Devices
State-of-the-art behavioral synthesis tools for reconfigurable architectures barely have high-level transformations in order to achieve highly parallelized implementations. If any, they apply loop unrolling to obtain a higher throughput. In this paper, we use the PARO behavioral synthesis tool which has the unique ability to perform both loop unrolling or loop partitioning. Loop unrolling repli...
متن کاملA Framework for Quantitative Comparison of Bilateral Teleoperation Systems Using μ-Synthesis
This paper presents a quantitative comparison framework for bilateral teleoperation systems which have different dynamic characteristics and sensory configurations for a given Task Dependant Performance Objective. μ-synthesis is used to develop the framework since it can efficiently treat systems containing uncertainties and disturbances. The framework consists of i) a feasibility test, and ii)...
متن کاملEcoScale, a semi-quantitative tool to select an organic preparation based on economical and ecological parameters
A novel post-synthesis analysis tool is presented which evaluates quality of the organic preparation based on yield, cost, safety, conditions and ease of workup/purification. The proposed approach is based on assigning a range of penalty points to these parameters. This semi-quantitative analysis can easily be modified by other synthetic chemists who may feel that some parameters should be assi...
