[amp_mcq option1=”Semantics of propositional logic” option2=”Alpha-beta pruning” option3=”First-order logic” option4=”Both Semantics of propositional logic & Alpha-beta pruning” correct=”option1″]
The correct answer is A. Semantics of propositional logic.
Semantics is the study of meaning, and in propositional logic, semantics is concerned with the meaning of propositional formulas. A propositional formula is a statement that can be either true or false. The semantics of propositional logic is used to determine the truth value of a propositional formula.
Alpha-beta pruning is a heuristic search algorithm that is used to prune branches of a search tree that are not promising. First-order logic is a formal system that is used to represent and reason about the world. It is a more expressive language than propositional logic, and it can be used to represent more complex concepts.
However, first-order logic is not as efficient as propositional logic, and it is not typically used to compute the truth of a sentence. Instead, propositional logic is typically used for this purpose.
Here is a brief explanation of each option:
- A. Semantics of propositional logic: Semantics is the study of meaning, and in propositional logic, semantics is concerned with the meaning of propositional formulas. A propositional formula is a statement that can be either true or false. The semantics of propositional logic is used to determine the truth value of a propositional formula.
- B. Alpha-beta pruning: Alpha-beta pruning is a heuristic search algorithm that is used to prune branches of a search tree that are not promising.
- C. First-order logic: First-order logic is a formal system that is used to represent and reason about the world. It is a more expressive language than propositional logic, and it can be used to represent more complex concepts.
- D. Both Semantics of propositional logic & Alpha-beta pruning: This is not a correct option. Semantics of propositional logic is used to compute the truth of any sentence, while alpha-beta pruning is a heuristic search algorithm that is used to prune branches of a search tree that are not promising.
