Questions and Answers
  • 1. 

    What is backtracking algorithm?

    • A.

      For computing

    • B.

      For finding improvement on computation problems

    • C.

      For practical jobs

    • D.

      A and B

    Correct Answer
    B. For finding improvement on computation problems
    Explanation
    The backtracking algorithm is a technique used to solve computational problems by incrementally building a solution and then "backtracking" or undoing certain steps if they are found to be incorrect or not leading to the desired solution. It is particularly useful for finding improvements on computation problems as it allows for exploring different possibilities and optimizing the solution. This algorithm is not limited to practical jobs or specific domains, but can be applied in a wide range of problem-solving scenarios.

    • A.

      Leo tape

    • B.

      Sound track

    • C.

      Back tracking

    • D.

      A and B

    Correct Answer
    C. Back tracking
    Explanation
    Backtracking is a design technique used in computer science and engineering. It involves solving problems by incrementally building a solution and backtracking or undoing certain steps when a dead end is reached. This technique is commonly used in algorithms like depth-first search and constraint satisfaction problems. Leo tape and sound track are not design techniques, while backtracking is a well-known technique used to solve a variety of problems.

    Which nodes reflect solution's component?

    • A.

      Leo tape

    • B.

      State space tree

    • C.

      Cardio

    • D.

      Vasco

    Correct Answer
    B. State space tree
    Explanation
    The correct answer is "State space tree." In problem-solving and search algorithms, a state space tree represents all possible states and transitions between them. It is a graphical representation of the problem's solution space, with each node representing a specific state and the edges representing the possible transitions between states. Therefore, the nodes in the state space tree reflect the components of the solution being searched for.

    JWhat's a feature of backtracking?

    • A.

      Optimization problems

    • B.

      No optimization problems

    • C.

      Technicality

    • D.

      None of the above

    Correct Answer
    B. No optimization problems
    Explanation
    Backtracking is a technique used to solve problems by incrementally building a solution and undoing the choices that lead to incorrect solutions. It is primarily used for solving problems that require finding a feasible solution rather than an optimal one. Therefore, the feature of backtracking is that it does not involve optimization problems.

      Cardio

    • D.

      Knight tour problem

    Correct Answer
    D. Knight tour problem
    Explanation
    The Knight tour problem involves backtracking because it requires finding a sequence of moves for a knight on a chessboard such that it visits every square exactly once. Backtracking is used in this problem to explore all possible moves and backtrack when a dead end is reached, allowing the algorithm to find the correct sequence of moves.

    • C.

      St standard international secret femen

    • D.

      None of the above

    Correct Answer
    B. Standard incremental search formulation
    Explanation
    The acronym SISF stands for Standard Incremental Search Formulation. This suggests that it is a standardized approach or method for conducting incremental searches. The other options provided do not accurately represent the meaning of the acronym.

    What does backtracking search do?

    • A.

      Formulates solution

    • B.

      Reduce redundancy

    • C.

      Reproves approach

    • D.

      Returns solution to backtracking

    Correct Answer
    D. Returns solution to backtracking
    Explanation
    Backtracking search is an algorithmic technique that is used to find solutions to problems by exploring all possible paths and backtracking when a solution is not found. It systematically explores the search space, making choices and undoing them if they lead to dead ends. When a solution is found, the algorithm returns that solution. Therefore, the correct answer states that backtracking search returns the solution to backtracking.

    What does MRV stand for?

    • A.

      Minimal review values

    • B.

      Micro remaining values

    • C.

      Minimum remaining values

    • D.

      None of the above

    Correct Answer
    C. Minimum remaining values
    Explanation
    MRV stands for Minimum Remaining Values. This term is commonly used in the context of constraint satisfaction problems, where it refers to a heuristic for selecting the next variable to be assigned a value. The MRV heuristic selects the variable with the fewest remaining possible values, aiming to reduce the branching factor and improve efficiency in the search process. In this case, the correct answer is "Minimum remaining values."

    What is a con of backtracking?

    • A.

      A lot of redundant work

    • B.

      Wastes time

    • C.

      Implemented

    • D.

      A and B

    Correct Answer
    A. A lot of redundant work
    Explanation
    A con of backtracking is that it involves a lot of redundant work. This means that the algorithm may end up revisiting the same states or making the same calculations multiple times, which can be inefficient and time-consuming. This can lead to longer execution times and increased computational resources being used.

    What is backtracking trashing?

    • A.

      It thrashes unnecessary work

    • B.

      It reduces cache

    • C.

      All of the above

    • D.

      None of the above

    Correct Answer
    A. It thrashes unnecessary work
    Explanation
    Backtracking trashing refers to the process of discarding unnecessary work or computations in order to optimize performance. It involves selectively undoing or discarding previously made choices or decisions in a problem-solving algorithm. By eliminating unnecessary work, backtracking trashing helps to improve efficiency and reduce the time and resources required to solve a problem. Therefore, the given answer "It thrashes unnecessary work" accurately describes the concept of backtracking trashing.
