👉 Non-exhaustiveness is a fundamental concept in computational complexity theory, particularly in the study of NP-complete problems and related areas. It refers to a problem that has a solution but does not necessarily provide an efficient algorithm for finding such a solution. In other words, a problem is said to be non-exhaustive if there exists a polynomial-time computable function $f$ such that any instance of the problem can be transformed into an instance with only one bit set in its input. This transformation means
