PSPACEhardness
PSPACE-hardness is a concept in computational complexity theory that describes the difficulty of a computational problem. A problem is considered PSPACE-hard if every problem in the class PSPACE can be reduced to it in polynomial time. This means that solving the PSPACE-hard problem would imply the ability to solve any problem in PSPACE, which is a class of problems that can be solved using polynomial space.
PSPACE-hardness is a measure of the inherent difficulty of a problem, but it does not necessarily mean
The concept of PSPACE-hardness is important in understanding the limitations of computational resources. It helps in
