Abstract Interpretation Idea

This lecture introduces the concept of abstract interpretation as a method to infer properties of program computations. It covers the basic idea, abstract states, fixpoints, control-flow graphs, and sets of states at program points. The lecture also discusses proving through fixpoints of approximate functions, reachable states as recursive equations, and analysis domains. It explains the approximation of sets, transfer functions, and updating sets in the context of program meaning and recursive equations.
