How to represent waypoints and partial results in hierarchical goal stacks?
Question from Randy Jones: Suppose that you have a problem-space structure something along the following lines: top-ps execute-mission racetrack Inside the racetrack problem space, we want to set an O-supported flag (based on our current position) marking that the racetrack waypoint was achieved. In Soar 8, we can’t put that flag on the racetrack state, because as soon as our position changes the whole racetrack state will get retracted (right?). So instead I put flag up on the top-ps state. Now the problem is that I have to clean up after myself. I need to clean up that flag when the racetrack operator is gone. Is there an “approved” way to do this? Or has someone done this and developed a clean way? One possibility I can think of is that I propose a clean-up-racetrack operator (in the execute-mission problem-space) that is worse than the racetrack operator (and conditional on the existence of the O-supported stuff I want to delete). This makes the clean-up-racetrack operator wait unt
