Which of the following best describes Backtracking?
Difficulty: Hard
About this MCQ
This Hard Algorithms question asks: Which of the following best describes Backtracking? The correct choice is D. An algorithmic technique that incrementally builds candidates and abandons ones that fail to satisfy constraints.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Algorithms items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Algorithms so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Algorithms item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. An algorithm that finds the shortest path between nodes in a graph with non-negative edge weights.
Why not A: “An algorithm that finds the shortest path between nodes in a graph with non-negative edge weights.” does not fit this question. The answer is An algorithmic technique that incrementally builds candidates and abandons ones that fail to satisfy constraints..
- B. An algorithmic technique that solves problems by breaking them into overlapping subproblems and storing results.
Why not B: “An algorithmic technique that solves problems by breaking them into overlapping subproblems and storing results.” does not fit this question. The answer is An algorithmic technique that incrementally builds candidates and abandons ones that fail to satisfy constraints..
- C. A search algorithm that repeatedly divides a sorted array in half to locate a target value.
Why not C: “A search algorithm that repeatedly divides a sorted array in half to locate a target value.” does not fit this question. The answer is An algorithmic technique that incrementally builds candidates and abandons ones that fail to satisfy constraints..
- D. An algorithmic technique that incrementally builds candidates and abandons ones that fail to satisfy constraints. ✓
Correct answer
D. An algorithmic technique that incrementally builds candidates and abandons ones that fail to satisfy constraints.
Explanation
An algorithmic technique that incrementally builds candidates and abandons ones that fail to satisfy constraints is the term that matches Which of the following best describes Backtracking option D Option A An algorithm that finds the shortest path between nodes in a graph with non-negative edge weights does not fit this question Option B An algorithmic technique that solves problems by breaking them into overlapping subproblems and storing results does not fit this question Option C A search algorithm that repeatedly divides a sorted array in half to locate a target value does not fit this question For this Algorithms question the accepted answer is An algorithmic technique that incrementally.
