  2. DTIME - Wikipedia

    en.wikipedia.org/wiki/DTIME

    In computational complexity theory, DTIME (or TIME) is the computational resource of computation time for a deterministic Turing machine. It represents the amount of time (or number of computation steps) that a "normal" physical computer would take to solve a certain computational problem using a certain algorithm. It is one of the most well ...

    en.wikipedia.org/wiki/Wold's_theorem

    In statistics, Wold's decomposition or the Wold representation theorem (not to be confused with the Wold theorem that is the discrete-time analog of the Wiener–Khinchin theorem), named after Herman Wold, says that every covariance-stationary time series can be written as the sum of two time series, one deterministic and one stochastic.

  4. Silver–Meal heuristic - Wikipedia

    en.wikipedia.org/wiki/Silver–Meal_heuristic

    The Silver–Meal heuristic is a production planning method in manufacturing, composed in 1973 [1] by Edward A. Silver and H.C. Meal. Its purpose is to determine production quantities to meet the requirement of operations at minimum cost.

  5. Deterministic time hierarchy theorem - Wikipedia

    en.wikipedia.org/wiki/Time_hierarchy_theorem

    Time Hierarchy Theorem. If f(n) is a time-constructible function, then there exists a decision problem which cannot be solved in worst-case deterministic time o(f(n)) but can be solved in worst-case deterministic time O(f(n)log f(n)).

  6. EXPTIME - Wikipedia

    en.wikipedia.org/wiki/EXPTIME

    In computational complexity theory, the complexity class EXPTIME (sometimes called EXP or DEXPTIME) is the set of all decision problems that are solvable by a deterministic Turing machine in exponential time, i.e., in O(2 p(n)) time, where p(n) is a polynomial function of n.

  7. NP (complexity) - Wikipedia

    en.wikipedia.org/wiki/NP_(complexity)

    NP is the set of decision problems solvable in polynomial time by a nondeterministic Turing machine. NP is the set of decision problems verifiable in polynomial time by a deterministic Turing machine. The first definition is the basis for the abbreviation NP; "nondeterministic, polynomial time". These two definitions are equivalent because the ...

  8. Uncertainty quantification - Wikipedia

    en.wikipedia.org/wiki/Uncertainty_quantification

    Given some experimental measurements of a system and some computer simulation results from its mathematical model, inverse uncertainty quantification estimates the discrepancy between the experiment and the mathematical model (which is called bias correction), and estimates the values of unknown parameters in the model if there are any (which ...

    Suppose is an unknown deterministic parameter that is to be estimated from independent observations (measurements) of , each from a distribution according to some probability density function (;). The variance of any unbiased estimator θ ^ {\displaystyle {\hat {\theta }}} of θ {\displaystyle \theta } is then bounded [ 12 ] by the reciprocal ...
