Definition of PSPACE. Meaning of PSPACE. Synonyms of PSPACE

- problems in PSPACE are also in PSPACE, meaning that co-PSPACE = PSPACE.[citation needed] The following relations are known between PSPACE and the complexity...
- In com****tional complexity theory, a decision problem is PSPACE-complete if it can be solved using an amount of memory that is polynomial in the input...
- also known to be no larger than PSPACE, the class of problems decidable in polynomial space. Again, whether P = PSPACE is an open problem. To summarize:...
- need not store game states; however many games of interest are known to be PSPACE-hard, and it follows that their space complexity will be lower-bounded by...
- hypothetical technologies List of NP-complete problems List of paradoxes List of PSPACE-complete problems List of undecidable problems List of unsolved deaths Lists...
- problems solvable by an interactive proof system. It is equal to the class PSPACE. The result was established in a series of papers: the first by Lund, Karloff...
- the classes NP and co-NP. Each class in the hierarchy is contained within PSPACE. The hierarchy can be defined using oracle machines or alternating Turing...
- exponential time, a very large class. NEXPTIME contains PSPACE, and is believed to strictly contain PSPACE. Adding a constant number of additional provers beyond...
- \exists z\ ((x\lor z)\land y)} QBF is the canonical complete problem for PSPACE, the class of problems solvable by a deterministic or nondeterministic Turing...
- Second-order logic with a transitive closure (commutative or not) yields PSPACE, the problems solvable in polynomial space. Second-order logic with a least...
