## Problem Solving Agents MCQ Questions

Problem Solving Agents MCQ thousands of selected MCQs for professional interviews, tests, and exams. by practicing these AI quizzes daily for 2 to 3 hours you will make you professional.

**What is the main task of a problem-solving agent?**

The problem-solving agents are one of the goal-based agents.

**What is Initial state + Goal state in Search Terminology?**

Problem Instance : It is Initial state + Goal state.

**What is Time Complexity of Breadth First search algorithm?**

Time Complexity of Breadth-First search algorithm is b^d.

**Depth-First Search is implemented in recursion with _______ data structure.**

Depth-First Search implemented in recursion with LIFO stack data structure.

**How many types are available in the uninformed search method?**

The five types of uninformed search methods are Breadth-first, Uniform-cost, Depth-first, Depth-limited, and Bidirectional search.

**Which data structure conveniently used to implement BFS?**

The queue is the most convenient data structure, but memory used to store nodes can be reduced by using circular queues.

**How many types of informed search methods are in artificial intelligence?**

The four types of informed search methods are best-first search, Greedy best-first search, A* search, and memory bounded heuristic search.

**Greedy search strategy chooses the node for expansion in ___________**

Sometimes minimum heuristics can be used, sometimes maximum heuristics function can be used. It depends upon the application on which the algorithm is applied.

**What is disadvantage of Greedy Best First Search?**

The disadvantage of Greedy Best First Search is that it can get stuck in loops. It is not optimal.

**Searching using query on Internet is, use of ___________ type of agent.**

Refer to the definitions of both types of agents.

**Is optimality and completeness exist in bidirectional search algorithm?**

Yes, optimality and completeness both exist in bidirectional search algorithm.

**When will the Hill-Climbing algorithm terminate?**

When no neighbor is having a higher value, the algorithm terminates fetching local min/max.

**A* algorithm is based on __________**

When no neighbor is having a higher value, the algorithm terminates fetching local min/max.Best-first-search is giving the idea of optimization and quick choose of path, and all these characteristic lies in A* algorithm.

**What is the heuristic function of greedy best-first search?**

**uniform-cost search expands the node n with the __________**

Uniform-cost search expands the node n with the lowest path cost. Note that if all step costs are equal, this is identical to breadth-first search.

**When is breadth-first search is optimal?**

Because it always expands the shallowest unexpanded node.

**Which of the following search algorithm searches forward from initial state and backward from goal state till both meet to identify a common state?**

Bidirectional Search searches forward from the initial state and backward from goal state till both meets to identify a common state.

**The process of removing detail from a given state representation is called ______**

The process of removing detail from a representation is called abstraction.

**What is Space Complexity of Depth First search algorithm?**

**What is Branching Factor?**

Branching Factor: The average number of child nodes in the problem space graph.
