Question

Mathematical induction is used to prove the correctness of which type of algorithms?

1) Recursive algorithms
2) Iterative algorithms
3) Divide and conquer algorithms
4) Greedy algorithms

Answer 1

Mathematical induction is used to prove the correctness of recursive algorithms, although it can be applied to other types of algorithms as well.

Step-by-step explanation:

Mathematical induction is a form of inductive reasoning, which is used to prove the correctness of recursive algorithms primarily. This proof technique is powerful in demonstrating that a property holds for all natural numbers, starting with a base case and then showing that if it holds for an arbitrary case n, it also holds for n+1. Recursive algorithms, particularly, can be naturally approached with mathematical induction due to their self-referential nature, where the solution to a problem depends on solutions to smaller instances of the same problem.

Iterative algorithms, divide and conquer algorithms, and greedy algorithms can also potentially be analyzed and proven correct using induction or other methods, but they are not as inherently predisposed to inductive proofs as recursive algorithms are. Inductive reasoning is a powerful tool in algorithm design and analysis, reinforcing the reliability of algorithms across various problem domains.
