Final answer:
An algorithm with a polynomial runtime is considered efficient.
Step-by-step explanation:
An algorithm with a polynomial runtime is considered efficient.
In computer science, the runtime of an algorithm is a measure of its efficiency, with polynomial runtimes being generally considered efficient. Polynomial runtimes, such as O(n^2) or O(n^3), grow at a reasonable rate as the input size increases.
Examples of polynomial runtimes include algorithms like bubble sort, insertion sort, and matrix multiplication.
