Model checking is a promising approach to automatic verification, which has concentrated on specification expressed in temporal logics. Comparatively little attention has been given to temporal logics of knowledge, although such logics have been proven to be very useful in the specifications of protocols for distributed systems. In this paper, we address(More)
We present a new computational model of BDI-agents, called the observation-based BDI-model. The key point of this BDI-model is to express agents' beliefs, desires and intentions as a set of runs (computing paths), which is exactly a system in the interpreted system model, a well-known agent model due to Halpern and his colleagues. Our BDI-model is(More)
We present an approach to the verification of temporal epistemic properties in synchronous multi-agent systems (MAS) via bounded model checking (BMC). Based on the semantics of synchronous interpreted system, we extend the temporal logic <i>CTL</i>* by incorporating epistemic modalities and obtain the so-called temporal epistemic logic <i>CTL*K.</i> Though(More)
We present a bounded model checking (BMC) approach to the verification of temporal epistemic properties of multi-agent systems. We extend the temporal logic CT L * by incorporating epistemic modalities and obtain a temporal epistemic logic that we call CT L * K. CT L * K logic is interpreted under the semantics of synchronous interpreted systems. Though CT(More)
We model the Sum and Product Riddle in public announcement logic, which is interpreted on an epistemic Kripke model. The model is symbolically represented as a finite state program with n agents. A model checking method to the riddle is developed by using the BDD-based symbolic model checking algorithm for logic of knowledge we developed in [7]. The method(More)
The present study used an in vitro model of cold cardioplegia in isolated working rat hearts to evaluate the possible role of ethyl pyruvate (EP) in promoting cardiac function and preventing apoptosis. Two groups of rats were evaluated; the EP (2 mM EP; n=8) and control (n=8) groups. Isolated rat hearts were perfused with Krebs-Henseleit buffer (KHB) for 30(More)
