WebOct 1, 1997 · Reviewer: Julian Stuart Williams The authors define a quantum Turing machine (QTM) analogously to the classic Turing machine as a triplet S ,Q, d , where S is a finite alphabet with an identified blank symbol #, Q is a finite set of states with an identified initial state q 0 and a final state q f ?q 0 , and d , the quantum transition function, is a function … 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. Intuitively, this says that if one writes a function that is polynomial-time … See more In descriptive complexity, P can be described as the problems expressible in FO(LFP), the first-order logic with a least fixed point operator added to it, on ordered structures. In … See more A generalization of P is NP, which is the class of decision problems decidable by a non-deterministic Turing machine that runs in polynomial time. Equivalently, it is the class of decision problems where each "yes" instance has a polynomial size certificate, and … See more Some problems are known to be solvable in polynomial time, but no concrete algorithm is known for solving them.
