Detailed explanation-1: -What Is the No Free Lunch Theorem? The No Free Lunch Theorem, often abbreviated as NFL or NFLT, is a theoretical finding that suggests all optimization algorithms perform equally well when their performance is averaged over all possible objective functions.
Detailed explanation-2: -The no-free-lunch theorem of optimization (NFLT) is an impossibility theorem telling us that a general-purpose, universal optimization strategy is impossible. The only way one strategy can outperform another is if it is specialized to the structure of the specific problem under consideration.
Detailed explanation-3: -The name alludes to the saying “there ain’t no such thing as a free lunch", that is, there are no easy shortcuts to success.
