Center node: "robustness analysis for value freezing signal temporal logic"
  Abstract: In our previous work we have introduced the logic STL*, an#N#extension of Signal Temporal Logic (STL) that allows value#N#freezing. In this paper, we define robustness measures for STL*#N#by adapting the robustness measures previously introduced for#N#Metric Temporal Logic (MTL). Furthermore, we present an#N#algorithm for STL* robustness computation, which is implemented#N#in the tool Parasim. Application of STL* robustness analysis is#N#demonstrated on case studies.
