What are present in each level of planning graph?
a) Literals
b) Actions
c) Variables
d) Both Literals & Actions
Explanation: Each and every level in the planning graph contains a set of literals and a set of actions.
Which kind of problem is suitable for planning graph?
a) Propositional planning problem
b) Planning problem
c) Action problem
d) None of these
Explanation: Planning graph work only for propositional planning problem with no variables.
What is meant by persistence actions?
a) Allow a literal to remain false
b) Allow a literal to remain true
c) Allow a literal to remain false & true
d) None of the mentioned
Explanation: Calculus allows a literal to remain true from one situation to the next if no action alters it. It is called as persistence action.
When will further expansion is unnecessary for
planning graph?
a) Identical
b) Replicate
c) Not identical
d) None of these
Explanation: Every subsequent levels will be identical, So further expansion is unnecessary.
How many conditions are available between two actions in mutex relation?
a) 1
b) 2
c) 3
d) 4
Explanation: The three conditions available on mute relationship are inconsistent effects, interference and competing needs.
What is called inconsistent support?
a) If two literals are not negation of other
