    Explanation
    The start state to solve the water jug problem should be 0,0 because in the problem, we are given two jugs, one of which can hold 4 liters of water and the other can hold 3 liters. The start state represents the amount of water in each jug, and since we haven't filled either of the jugs yet, the start state should be 0,0.

    Rate this question:

  • 18. 

    To generate all the offsprings of root & all successor of leaf nodes is what kind of search: 

    • A.

      BFS

    • B.

      DFS

    • C.

      None

    Correct Answer
    A. BFS
    Explanation
    BFS (Breadth-First Search) is the correct answer because it explores all the immediate children of a node before moving on to the next level of nodes. In this case, the root node and leaf nodes are mentioned, indicating that all the offsprings of the root (immediate children) and all the successors of the leaf nodes (immediate children) need to be generated. This matches the behavior of BFS, where it explores all the neighbors at the current level before moving on to the next level.

    Rate this question:

  • 19. 

    If only single branch of tree is search until it yields to a goal state is -------

    • A.

      DFS

    • B.

      BFS

    • C.

      None

    Correct Answer
    A. DFS
    Explanation
    DFS (Depth-First Search) is the correct answer because it explores a single branch of the tree until it reaches a goal state. It starts at the root node and explores as far as possible along each branch before backtracking. This means that it goes deep into the tree before exploring other branches, hence the name "depth-first". In contrast, BFS (Breadth-First Search) explores all the neighboring nodes of the current level before moving on to the next level, which does not fit the description given in the question.

    Rate this question:

  • 20. 

    Backtracking occurs in _______.

    • A.

      DFS

    • B.

      BFS

    • C.

      None

    Correct Answer
    A. DFS
    Explanation
    Backtracking occurs in DFS (Depth-First Search). DFS is a graph traversal algorithm that explores as far as possible along each branch before backtracking. It explores the deepest nodes first, and if a dead end is reached, it backtracks to the nearest node that still has unexplored branches. This process of backtracking allows DFS to search through all possible paths in a graph until it finds the desired solution or exhausts all possibilities. Therefore, the correct answer is DFS.

    Rate this question:

  • 21. 

    The following search does not guarantee a best answer but find a good one___________

    • A.

      Heuristic search

    • B.

      BFS

    • C.

      DFS

    Correct Answer
    A. Heuristic search
    Explanation
    Heuristic search is a type of search algorithm that does not guarantee finding the best answer, but it aims to find a good one. Unlike BFS (breadth-first search) and DFS (depth-first search), which systematically explore all possible paths, heuristic search uses heuristics or rules of thumb to guide the search towards more promising solutions. By considering the available information and making informed decisions, heuristic search can often find a satisfactory solution efficiently, even if it is not the optimal one.

    • A.

      Monotonic

    • B.

      Nonmonotonic

    Correct Answer
    A. Monotonic
    Explanation
    A production system in which the application of a rule never prevents the application of other rules is called "monotonic." This means that the rules can be applied independently of each other, and the application of one rule does not interfere with the application of other rules. In other words, the order in which the rules are applied does not matter, and there are no conflicts or dependencies between the rules.

    Rate this question:

  • 33. 

    In production system application of rule prevent application  of another rule ______.

    • A.

      Non-monotonic

    • B.

      Monotonic

    Correct Answer
    A. Non-monotonic
    Explanation
    In a production system, the application of a rule can prevent the application of another rule in a non-monotonic manner. This means that the application of a rule may lead to a change in the system's state, making it necessary to re-evaluate and potentially modify the application of other rules. This non-monotonic behavior allows for flexibility and adaptability in the system, as rules can be dynamically adjusted based on the current state and context.

    Rate this question:

  • 34. 

    Instead of matching the rules if current state is used as an index this matching technique is called as:

    • A.

      Indexing

    • B.

      Matching with variable

    Correct Answer
    A. Indexing
    Explanation
    The correct answer is "Indexing". In this matching technique, instead of matching the rules, the current state is used as an index. This means that the current state is used to directly access the corresponding rule or action. This approach is known as indexing because it involves using the current state as an index to retrieve the relevant information or rule.

    Rate this question:

    In the following technique, if the explore path exceeds the shortest path there is no need to continue exploration ________________.

    • A.

      Branch and bound

    • B.

      Heuristics

    Correct Answer
    A. Branch and bound
    Explanation
    Branch and bound is a technique used in optimization problems. It involves systematically exploring the search space by dividing it into smaller subproblems (branches) and keeping track of the best solution found so far (bound). If during the exploration process, the path being explored exceeds the length of the shortest path found, there is no need to continue exploring that particular branch. This is because any solution found in that branch will be worse than the current best solution, so it can be pruned, saving computational resources. Therefore, branch and bound is an efficient technique for finding optimal solutions by avoiding unnecessary exploration.

    • A.

      Steepest ascent hill climbing

    • B.

      Local maxima

    • C.

      Plato

    Correct Answer
    A. Steepest ascent hill climbing
    Explanation
    The concept of SUCC, which refers to the successor function, is included in steepest ascent hill climbing. This algorithm involves iteratively improving a solution by moving to a neighboring solution with a higher value. The successor function is used to generate these neighboring solutions, allowing the algorithm to climb towards the highest point in the search space. Local maxima and Plato are not directly related to the concept of SUCC or the successor function.

    A state is better then neighbor but not better than other further states is_________. 

    • A.

      Local maxima

    • B.

      Plato

    • C.

      Ridge

    Correct Answer
    A. Local maxima
    Explanation
    A state being better than its neighbor but not better than other further states suggests that it is at a peak or high point within its immediate surroundings. This concept is known as a local maxima, where the state has reached a relatively optimal or maximum level compared to its neighboring states, but there could still be other states further away that are even better.

    Consider local to heuristic, +1 for block resting on the thing and -1 for block resting on the wrong thing, what is value for series of block S, B-C-D-A Where A is on top________.

    • A.

      0

    • B.

      1

    • C.

      2

    • D.

      3

    Correct Answer
    A. 0
    Explanation
    The value for the series of blocks S, B-C-D-A where A is on top is 0. This means that there is no additional value or penalty for A being on top. The local to heuristic considers whether the block is resting on the correct thing (+1) or the wrong thing (-1), but in this case, there is no mention of any specific thing that A should be resting on. Therefore, the value remains at 0.

    The combination of hill climbing and random search is ______________.

    • A.

      Simulated annealing

    • B.

      Hill climbing

    • C.

      Local maxima

    Correct Answer
    A. Simulated annealing
    Explanation
    Simulated annealing is the correct answer because it is a combination of hill climbing and random search. Hill climbing is a local search algorithm that continuously moves towards better solutions, while random search explores the search space randomly. Simulated annealing combines these two approaches by initially allowing random movements to escape local optima, and then gradually reducing the randomness to converge towards the global optimum. Therefore, simulated annealing is a powerful optimization technique that combines the benefits of both hill climbing and random search.

    While running a prolog program the output is shown in following panel_______.

    • A.

      Message

    • B.

      Trigs

    • C.

      Dialog

    Correct Answer
    C. Dialog
    Explanation
    The correct answer is "Dialog" because when running a Prolog program, the output is typically shown in a dialog panel. This panel allows for interactive communication between the user and the program, displaying messages, prompts, and results of queries. This is where the program can ask for user input or display the output of the program's execution.

    Any factual expression in prolog program is called as ________.

    • A.

      Clauses

    • B.

      Predicates

    • C.

      Both

    • D.

      None

    Correct Answer
    A. Clauses
    Explanation
    In Prolog, any factual expression is called a clause. A clause is a fundamental unit of Prolog programming, representing a fact or a rule. It consists of a head and a body, separated by a ":-" operator. The head represents the predicate, which is the name of the clause, and the body represents the arguments or conditions associated with the predicate. Therefore, the correct answer for this question is "Clauses".

    Prolog is not suited for _____.

    • A.

      Numeric computation

    • B.

      Non Numeric computation

    • C.

      Object & relation problem

    Correct Answer
    A. Numeric computation
    Explanation
    Prolog is not suited for numeric computation because it primarily focuses on symbolic computation and logical inference. While Prolog can handle basic arithmetic operations, it lacks the efficiency and precision required for complex numerical calculations. Prolog's strength lies in its ability to manipulate symbolic data and perform logical reasoning, making it more suitable for tasks such as natural language processing, expert systems, and rule-based problem solving.

    A relationship can have any no of object.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because a relationship can have any number of objects involved. In the context of relationships between individuals, there can be multiple people involved in a relationship, such as friendships, families, or romantic partnerships. Similarly, in the context of database relationships, a relationship can connect multiple objects or entities. Therefore, there is no restriction on the number of objects that can be part of a relationship.

    Conjunction in Prolog is performed by which notation ______.

    • A.

      ,

    • B.

      :

    • C.

      ;

    • D.

      !

    Correct Answer
    A. ,
    Explanation
    Conjunction in Prolog is performed by the notation ",". In Prolog, a conjunction is used to combine multiple goals or conditions, and the comma acts as a logical "and" operator. When goals are separated by a comma, Prolog evaluates them one by one, and all goals must succeed for the conjunction to be true.

    Disjunction in Prolog is performed using _____.

    • A.

      ,

    • B.

      :

    • C.

      ;

    • D.

      !

    Correct Answer
    C. ;
    Explanation
    In Prolog, disjunction is performed using the semicolon (;) operator. This operator allows for multiple clauses or goals to be evaluated, and the program will backtrack and try alternative solutions if necessary. The semicolon acts as an OR operator, meaning that if any of the clauses or goals separated by the semicolon are true, the overall disjunction is considered true.
