We present and compare different Boolean encodings of the transition relation for the parallel composition of transition systems, both for the asynchronous and the synchronous semantics. We compare the encodings considered by applying them to the SAT-based bounded model checking (BMC) of ECTL∗ properties. We provide experimental results which show that our new encoding for the asynchronous sema...

Bounded model checking (BMC) based on satisfiability testing (SAT) has been introduced as a complementary technique to BDDbased symbolic model checking of LTL properties in recent years and a lot of successful work has been done with this approach. The basic idea is to search for a counter example of a particular length and to generate a propositional formula that is satisfied iff such a counte...

Agents are becoming increasingly common as a means of structuring interactive systems, due to the highly complex and concurrent nature of modern systems. The manner in which interaction between these agents is specified is of fundamental importance, and must pay heed to expressivity and reuse concerns. There are also concerns specific to interactive systems, and in particular the need to specif...

Both workflow and agent technology have recently been applied to business process management. The integration of these two technologies will definitely provide solutions to the problems not to be solved by any of them. This paper summaries the capabilities of these two technologies and discusses the forms and their benefits of integrating them for business process management. Generally, agent e...

The work reported in this article presents a computational model of interpretation. The model proposes a cognitive architecture for intelligent agents to reason about competing analyses during interpretation and leverages the positive reinforcement principle.

Intelligent virtual agents are typically embedded in a social environment and must reason about social cause and effect. Social causal reasoning is qualitatively different from physical causal reasoning that underlies most current intelligent systems. Besides physical causality, the assessments of social cause emphasize epistemic variables including intentions, foreknowledge and perceived coerc...

The aim of this paper is to describe some theoretical considerations about virtual character design. In recent years, many prototypes of cognitive and behavioral architectures have been developed to simulate human behavior in artificial agents. Analyzing recent studies, we assume that there exists a variety of computational models and methods in order to increase the cognitive abilities of the ...

This paper introduces an agent-based model in which selfinterest intelligent agents are adaptive. Agents can either go to find resources in the environment or mine the resources found. Agents trade information about resources in a market. A biased learning mechanism is introduced to update agents’ capabilities of mining and searching. The learning mechanism plays a vital role in the specializat...

Abstract. This paper describes an experiment in studying coordination in intelligent agent societies in terms of state-variable models. An overview of the modeling framework is first provided. The architectural foundation for the modeling approach is then described. This description is followed by a sample application of the methodology in analyzing a coordination scenario. A simulation of the ...
