Center node: "what is known about the value 1 problem for probabilistic automata"
  Abstract: The value 1 problem is a decision problem for probabilistic automata over finite words: are there words accepted by the automaton with arbitrarily high probability? Although undecidable, this problem attracted a lot of attention over the last few years. The aim of this paper is to review and relate the results pertaining to the value 1 problem. In particular, several algorithms have been proposed to partially solve this problem. We show the relations between them, leading to the following conclusion: the Markov Monoid Algorithm is the most correct algorithm known to (partially) solve the value 1 problem.

Connected through hyperedge HE-1 (induced by source paper "deciding the value 1 problem for probabilistic leaktight automata"):

    - "decidable problems for probabilistic automata on infinite words"
    - "algorithms for omega regular games with imperfect information"
