In computational complexity theory, P, also known as PTIME or DTIME(n ), is a fundamental complexity class. It contains all decision problems that can be solved by a deterministic Turing machine using a polynomial amount of computation time, or polynomial time. Cobham's thesis holds that P is the class of … See more A language L is in P if and only if there exists a deterministic Turing machine M, such that • M runs for polynomial time on all inputs • For all x in L, M outputs 1 See more P is known to contain many natural problems, including the decision versions of linear programming, and finding a maximum matching. … See more Polynomial-time algorithms are closed under composition.

Web– A reusable garbling scheme for any polynomial-time Turing machine. These three schemes have the property that the size of a key or of a garbling for a Turing machine is very short: it depends only on the description of the Turing machine and not on its running time. Previously, the only existing constructions of such schemes were for depth-d WebNotably, 2SAT can be solved in polynomial time, unlike 3SAT. It seems like this distinction would be important to mention in such an article, for the benefit of those who are not familiar with the subject.
