For brevity, in the sequel we exclude the variables from the presentation. • Effects – We assume that an execution of a particular action in an environment in which certain facts and events hold, will modify a given fact: a causes f if p1 , . . , pn , e1 , . . , em (1) The intuitive meaning is that the execution of the action a in a in which each fact pi (i ∈ {1, . . , n}) is true and each (primitive and/or composite) event ej (j ∈ {1, . . , m}) has been detected, ensures that the fact f is true in the state resulting from the execution of the action.
