PSPACE In complexity theory the class PSPACE, which equals NPSPACE by Savitch's theorem, is the set of decision problems that can be solved by a deterministic or nondeterministic Turing machine using a polynomial amount of memory and unlimited time (either of these machine types determines the same class).
PSPACE-complete In complexity theory, a decision problem is PSPACE-complete if it is in PSPACE and every problem in PSPACE can be reduced to it in polynomial time. The problems that are PSPACE-complete can be thought of as the hardest problems in PSPACE.
PSPACE-hard A decision problem p is said to be PSPACE-hard if, given any decision problem q in PSPACE, q can be reduced to p in polynomial time. PSPACE-hardness is distinguished from PSPACE-completeness by the fact that PSPACE-hardness does not require the problem to be in PSPACE.
