Adding Intervals to Temporal Planning about unified-planning

[alexander-sung]

I'd like to add to the relevance of this issue since I'm currently trying to model a problem which has certain fluents set to specific values in some intervals in the future. My understanding is that problem.set_initial_value(robot_at(l1), True, interval=Interval()), as an example, is addressing this.

Additionally, is mentioning actions in the user story also covering actions already being executed at planning time? Referring to the example from https://colab.research.google.com/github/aiplan4eu/unified-planning/blob/master/notebooks/Unified_Planning_Temporal.ipynb, let's say I'm executing the first plan received for 3 seconds but then notice one of the planned matches is broken and I need to replan to use another. At this point in time I would like to specify that one match is already in use, thus giving light. On the other hand, a fuse is currently being mended, so that hand is not free. Instead of reproducing all the actions' effects, it would be convenient to specify actions already being executed. Is this covered here? Otherwise I would create a separate user story, no problem. Let me know in case that's preferred. Thanks.

@uwe-koeckemann Closing this for now: we do have some interval support in temporal and hierarchical planning, but no engines generally support very expressive interval reasoning (at least for now...)
