| Abstract [en]: |
We propose an approach to modeling delayed effects of actions which is
based on the use of causal constraints and their interaction with the
direct effects of actions. The approach extends previous work with a
causal approach used to deal with the ramification problem. We show
the similarity between solutions to the modeling of indirect effects
and delayed effects of actions by example. The base logic PMON+ is
a temporal logic for reasoning about action and change and uses
circumscription. It is shown that the extension for delayed effects
of actions retains the first-order reducibility property shown
previously for successfully dealing with the frame and ramification
problems for a large class of action scenarios. We also consider the
“causal qualification” problem, "natural death" of fluents and causal
lag, each of which is closely related to the use of delayed effects. |
