Select one:

b. Generate-and-test
c. Backtracking
d. None of these answers
Question:
A/An ______________ has either a false or a normal atom at its
head.
Ans: Horn
clause
Horn clause is a clause that has either a definite clause or maybe an Integrity constraint which typically implies that it has either a false or a normal atom at its head.
Question:
The following statement: “check each total assignment in turn; if
an assignment is found that satisfies all of the constraints,
return that assignment” describes which CSP algorithm?
Ans: Generate and
test
Generate and Test algorithm follows this approach:
- Firstly, generate the possible solutions which mean generating a
path from a start state to find solutions.
- Then it will test the solution which is found by comparing it
with the endpoint.
- Then if the solution is found, it will return the solution
otherwise return to the main step.
When we check the statement which is mentioned, we can see the
approach of the Generate and Test algorithm.
