                 planning problems defined in the SAS+ formalism. This
                 report complements these results by providing a
                 complete map over the complexity of SAS+ planning under
                 all combinations of the previously considered
                 restrictions. We analyze the complexity both of finding
                 a minimal plan and of finding any plan. In contrast to
                 other complexity surveys of planning we study not only
                 the complexity of the decision problems but also of the
                 generation problems. We prove that the SAS+-PUS problem
                 is the maximal tractable problem under the restrictions
                 we have considered if we want to generate minimal
                 plans. If we are satisfied with any plan, then we can
                 generalize further to the SAS+-US problem, which we
                 prove to be the maximal tractable problem in this
                 case.",
