Comparing MRP and STRIPS
Model-based Reactive Planning
Action representation
- state transitions ??
- co-temporal interactions ??
State variables change through transitions or through interactions.
Transitions are controlled by establishing control values which interact with internal variables.
State changes may not be preventable.
Enabling one transition may necessarily cause a second transition to occur.
Action representation
- strips operators with precondition and add/delete as effects.
State variables only change directly by operator add/delete.
Operators are invoked directly
State is held constant when operators are not invoked.
Operators are invoked one at a time.
