Signal temporal logic (STL) is a formalism used to rigorously specify requirements of cyberphysical systems (CPS), i.e., systems mixing digital or discrete components in interaction with a continuous environment or analog components. STL is naturally equipped with a quantitative semantics which can be used for various purposes: from assessing the robustness of a specification to guiding searches over...
We consider the problem of designing an automatic grader for a laboratory in the area of cyber-physical systems. The goal of this laboratory is to program a robot for specified navigation tasks. Given a candidate student solution (control program for the robot), our grader first checks whether the robot performs the task correctly under a representative set of environment conditions. If it does not,...
The classical formulation of the program-synthesis problem is to find a program that meets a correctness specification given as a logical formula. Recent work on program synthesis and program optimization illustrates many potential benefits of allowing the user to supplement the logical specification with a syntactic template that constrains the space of allowed implementations. Our goal is to identify...
