  - POMDPs are standard models for probabilistic planning problems, where an agent
    interacts with an uncertain environment. We study the problem of almost-sure reachability,
    where given a set of target states, the question is to decide whether there is
    a policy to ensure that the target set is reached with probability 1 (almost-surely).
    While in general the problem is EXPTIMEcomplete, in many practical cases policies
    with a small amount of memory suffice. Moreover, the existing solution to the
    problem is explicit, which first requires to construct explicitly an exponential
    reduction to a belief-support MDP. In this work, we first study the existence
    of observation-stationary strategies, which is NP-complete, and then small-memory
    strategies. We present a symbolic algorithm by an efficient encoding to SAT and
    using a SAT solver for the problem. We report experimental results demonstrating
    the scalability of our symbolic (SAT-based) approach. © 2016, Association for
