Answer these questions on planning explaining your reasoning briefly but precisely: 1. Why preconditions in action schemas are conjunctions and, for most of the planners, not disjunctions? 2. Why an initial state for planning needs to have ground atoms (no variables)? 3. Why variables that appear in the effects of an action schema have to be in the preconditions? 4. What is the closed world assumption and why it is used in planning?
