Efficient Analysis of Probabilistic Programs with an Unbounded Counter

Published: 17 December 2014 Publication History

Abstract

We show that a subclass of infinite-state probabilistic programs that can be modeled by probabilistic one-counter automata (pOC) admits an efficient quantitative analysis. We start by establishing a powerful link between pOC and martingale theory, which leads to fundamental observations about quantitative properties of runs in pOC. In particular, we provide a “divergence gap theorem”, which bounds a positive non-termination probability in pOC away from zero. Using these observations, we show that the expected termination time can be approximated up to an arbitrarily small relative error in polynomial time, and the same holds for the probability of all runs that satisfy a given ω-regular property encoded by a deterministic Rabin automaton.

    The authors consider a probabilistic recursive program working on data of unbounded size, for example, with a geometric probability distribution for what the data looks like. This makes sense for common data structures like trees. Is the expected time that the program will terminate finite__?__ Is it almost sure (probability 1) that all runs, finite and infinite, satisfy a property specified by a deterministic Rabin automaton on infinite words__?__ When the program can be modeled as a probabilistic one-counter automaton, the authors show such questions can be answered in polynomial time. An earlier work considered more general probabilistic pushdown systems, but used the decidability of the existential theory of the reals, which has greater complexity. The main idea is that although the system is modeled as an infinite Markov chain, the questions can be answered by analyzing another finite Markov chain with some "good" conditions. The paper is quite technical; the justification that these ideas are correct involves the construction of suitable martingales. Online Computing Reviews Service
