👉 Unhardness is a concept in mathematics and computational complexity theory that refers to the difficulty of proving or disproving an NP-hard problem. It is often used to describe problems whose solutions are not provable using current computational techniques, but which can still be solved by certain algorithms. In other words, unhardness means that there are no known polynomial-time algorithms for solving a particular NP-hard problem. This is different from the concept of "uncomputability," which refers to the inability to compute an
