Abstract

We show that the controller synthesis and verification problems for Markov decision processes with qualitative PECTL*objectives are 2-EXPTIMEcomplete. More precisely, the algorithms are polynomialin the size of a given Markov decision process and doubly exponential in the size of a given qualitative PECTL*formula. Moreover, we show that if a given qualitative PECTL*objective is achievable by somestrategy, then it is also achievable by an effectively constructible one-counterstrategy, where the associated complexity bounds are essentially the same as above. For the fragment of qualitative PCTL objectives, we obtain EXPTIMEcompleteness and the algorithms are only singly exponential in the size of the formula.
