The current generation of automated reasoning techniques excel at the qualitative tasks (i.e., when the answer is Yes or No) owing to the dramatic progress in satisfiability solving, also referred to as the SAT revolution. Such techniques sufficed to reason about traditional systems whose design sought to achieve deterministic behavior. In contrast, modern computing systems crucially rely on statistical methods to account for the uncertainty in the environment. To reason about the behavior of these systems in uncertain environments, there is a need to look beyond qualitative symbolic reasoning techniques. 

In this talk, I will discuss the design of the next generation of automated reasoning techniques to perform higher-order tasks such as quantitative measurement (aka counting), sampling of representative behavior, and automated synthesis of systems. Naturally, these tasks are hard from a complexity-theoretic viewpoint, and therefore, our frameworks focus on tight integration of real-world applications, beyond the worst-case analysis algorithmic design and data-driven system design. This has allowed us to obtain breakthrough results in counting, sampling, and synthesis, providing a new algorithmic toolbox in formal methods, probabilistic reasoning, and design verification, and enabling the transition from Beyond “SAT Revolution” to “Beyond SAT” Revolution. I will discuss the core design principles and the utility of the above techniques on various real applications, including neural network verification, critical infrastructure reliability, quantitative information-flow analysis, and design verification.
