Findings from Chinese Academy of Science in the Area of Information Technology Reported

June 19, 2014



By a News Reporter-Staff News Editor at Computer Technology Journal -- New research on Information Technology is the subject of a report. According to news reporting out of Beijing, People's Republic of China, by VerticalNews editors, research stated, "In this paper we offer an efficient controller synthesis algorithm for assume-guarantee specifications of the form. Here, are all safety-MTL properties, where the sub-formulas are supposed to specify assumptions of the environment and the sub-formulas are specifying requirements to be guaranteed by the controller."

Our news journalists obtained a quote from the research from the Chinese Academy of Science, "Our synthesis method exploits the engine of Uppaal-Tiga and the novel translation of safety- and co-safety-MTL properties into under-approximating, deterministic timed automata. Our approach avoids determinization of Buchi automata, which is the main obstacle for the practical applicability of controller synthesis for linear-time specifications. The experiments demonstrate that the chosen specification formalism is expressive enough to specify complex behaviors. The proposed approach is sound but not complete. However, it successfully produced solutions for all the experiments."

According to the news editors, the research concluded: "Additionally we compared our tool with Acacia+ and Unbeast, state-of-the-art LTL synthesis tools; and our tool demonstrated better timing results, when we applied both tools to the analogous specifications."
