What is the oracle assumption?

The oracle assumption refers to a theoretical premise in computational complexity theory where a decision problem can be solved efficiently using an "oracle" that provides answers to specific queries instantly. This concept is often used in the context of complexity classes, such as NP and P, to explore the limits of what can be computed efficiently. The assumption helps researchers understand the potential power of algorithms and the relationship between different complexity classes, although it is not generally achievable in practical scenariOS.
