Solving games via three-valued abstraction refinement

Abstract: Games that model realistic systems can have very large state spaces, making their direct solution difficult. We present a symbolic abstraction-refinement approach to the solution of two-player games with reachability or safety goals. Given a reachability or safety property, an initial set of states, and a game representation, our approach starts by constructing a simple abstraction of the game, guided by the predicates present in the property and in the initial set. The abstraction is then refined, until it is… Show more

“…These ideas are relevant and could be helpful in several variants of CEGAR: in model checking of quantitative specifications, where the query is not binary [7], in a CEGAR method for µ-calculus, where formulas need not have a universal or existential polarity [18], in attempts to refine the three-valued semantics [3], and in algorithms that gather batches of counterexamples before refining [14,15].…”

“…After the initial submission, every tool is tested on a small set of benchmarks from the SYNTCOMP library, and authors are informed about any problems and can submit bugfixes. 1 Ranking Schemes. In all tracks, there is a ranking based on the number of correctly solved problems: a correct answer within the timeout of 3600s is rewarded with one point for the solver, and a wrong answer is punished by subtracting 4 points.…”

“…Simple BDD Solver implements the standard BDD-based algorithm for safety games, including a large number of optimizations in configuration (basic). The other two configurations additionally implement an abstraction-refinement approach inspired by de Alfaro and Roy [1] in two variants: with overapproximation of the winning region in configuration (abs1), or with both over-and underapproximation in (abs2). The version entered into SYNTCOMP 2017 is the same as last year.…”

“…The first, which corresponds to A [6,16,18,21,22], where games combine may and must transitions, and also in settings in which games that are determined are approximated by means other than abstraction. For example, when LTL realizability is done by checking the realizability of approximations of both the specification and its negation [7].…”
