....which is exponential in the number of considered actions. 12 The occurrence of precondition conflicts and effect conflicts, respectively, in A ORC , result in the transition function to be undefined wrt. the considered action and state. For other interpretations of effect conflicts see [4] and [12]. 13 Recall, that the occupations represented by the signed fluents (and resources, resp. are resources which are intended to be combined non idempotent. Hence, they will be set off against each other like resource effects. The consumption of an occupation is, analogously, used for ....
