Planning asks to find a sequence of actions that will lead to achieving a given objective. Traditionally, this means that we are given an initial state (in terms of facts over some function-free first-order logic), (first-order) actions that can modify the state, and a goal state. This goal state is described in terms of a set of facts that we want to achieve simultaneously in the last state after executing the whole plan. In some scenarios this simple definition of the objective as a single goal state does not suffice. For example, we might want to describe that we shall first achieve objective A and only afterwards B, or that we want to achieve A without ever achieving B in the mean time. Further one might also want to describe infinite behaviour, i.e., a plan for running a factory machine indefinitely. For this purpose, the description of the objective can be formulated using Temporal Logic &#8212; and are then called &#8220;Temporally Extended Goals&#8221;.<br \/>\nIn the talk, I will give a brief introduction into planning. I will then turn to the way that temporally extended goals are usually described in planning and discuss the connection of this description language with Linear Temporal Logic. Lastly, I will give a brief overview of the possible ways to integrate Temporally Extended Goals into the planning process.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Gregor Behnke (ILLC, University of Amsterdam)<br \/>\nDate and Time: Thursday, June&nbsp;2nd 2022, 16:30-18:00, Amsterdam time.<br \/>\nVenue: online. &#8211; recording available, click here<br \/>\nTitle: Planning with Temporally extended Goals<br \/>\nAbstract.
