Question:
Which of the following search uses the problem specific knowledge beyond the definition of the problem ?
Which of the following search uses the problem specific knowledge beyond the definition of the problem ?
Show Hint
"Informed" means the agent has a "hint" (heuristic) about the direction of the goal, whereas "Uninformed" agents just wander systematically.

- Informed search
- Depth first search
- Breadth first search
- Uninformed search

The Correct Option is A
Solution and Explanation
Solution:
In Artificial Intelligence, search strategies are categorized based on whether they use additional information to guide the search process.
1. Uninformed Search:
Strategies like BFS and DFS (Options 2 and 3) are "blind." They only have access to the problem definition: the state space, transition rules, and the goal test. They have no "clue" how close a particular state is to the goal.
2. Informed Search:
Informed search (Option 1) uses a heuristic function ($h(n)$). This function represents problem-specific knowledge—such as the straight-line distance to a destination—that allows the algorithm to estimate the cost from the current state to the goal.
3. Logic:
Because Informed Search utilizes information outside the basic problem definition to find solutions more efficiently, it is the correct answer.

- Choose the correct answer from the options given below:
(A). RAID 3 requires only a single redundant disk.
(B) In RAID 4 scheme, two different parity calculations are carried out and stored in separate blocks on different disks.
(C) RAID 5 distributes the parity strips across all disks.
(D) In RAID 2, the number of redundant disks are proportional to the log of the number of data disks. - In case of DMA, after the completion of the transfer, the processor is required to be notified of the completion. This is done through.
- In a two-level memory hierarchy, the access time of the cache memory is 12 nsec and the access time of the main memory is 1.5 msec. The hit ratio is 0.98. What is the average access time of the two-level memory system?
- Match List I with List II.
List I List II A. Supervisor mode I. Entered when the processor encounters a software interrupt instruction B. Abort Mode II. Entered in response to memory fault C. Fast Interrupt Mode III. Entered whenever the processor receives an interrupt signal from a designated fast interrupt source D. Interrupt Mode IV. Entered whenever the processor receives an interrupt signal from any other source - Deallocation of stack of thread and register contexts will take place.
