Answer:A
Explanation: It will contain the list of goals containing a single element and returns the set of all substitutions satisfying the query. 4. How can be the goal is thought of in backward chaining algorithm?
A. Queue B. List C. Vector D. Stack
Explanation: The goals can be thought of as stack and if all of them us satisfied means, then current branch of proof succeeds. 5. What are used in backward chaining algorithm?
