👉 Probabilistic Dynamic Analysis (PDA) is a formal method used to verify the correctness of concurrent systems by modeling their behavior as probabilistic processes. It combines elements of model checking and stochastic analysis to reason about the likelihood of different outcomes in a system's execution. PDA represents the system's dynamics using probabilistic automata, where states are described by probability distributions rather than fixed values. This allows for the analysis of rare events, such as deadlock or livelock, which are difficult to detect with traditional methods. By calculating the probabilities of various system behaviors, PDA helps ensure that a system meets its reliability and safety requirements under all possible execution scenarios.
