Question

Which of the following is NOT true in problem solving in artificial intelligence?

• A. Implements heuristic search technique
• B. Solution steps are not explicit
• C. Knowledge is imprecise
• D. It works on or implements repetition mechanism

Answer 1

• 1. Heuristic search is a search technique that seeks to solve a problem by iteratively enhancing the solution using a heuristic function or a cost analysis. Heuristic search is two types. Direct Heuristic Search Techniques in AI( Breadth-First Search (BFS) and Depth First Search (DFS).) and Weak Heuristic Search Techniques in AI (Best-First Search, A* Search, etc)

• 2. Every AI program has to do the process of searching for the solution steps that are not explicit in nature.

• 3. knowledge plays a vital role in intelligence as well as creating artificial intelligence.

• ∴ Hence the incorrect statement is It works on or implements a repetition mechanism.

 

Answer 2

The statement "Solution steps are not explicit" is NOT true in problem-solving in artificial intelligence.

In problem-solving, especially in the context of heuristic search, the solution steps are often made explicit. Heuristic search algorithms aim to explore the search space efficiently, and the steps taken to reach the solution are typically tracked and recorded.

Therefore, the correct answer is:

Solution steps are not explicit
