Double exponential may refer to:
* A
double exponential function
** Double exponential time, a task with
time complexity
In theoretical computer science, the time complexity is the computational complexity that describes the amount of computer time it takes to run an algorithm. Time complexity is commonly estimated by counting the number of elementary operations ...
roughly proportional to such a function
**
2-EXPTIME, the
complexity class
In computational complexity theory, a complexity class is a set (mathematics), set of computational problems "of related resource-based computational complexity, complexity". The two most commonly analyzed resources are time complexity, time and s ...
of
decision problems solvable in double-exponential time by a deterministic Turing machine.
* Double exponential distribution, which may refer to:
**
Laplace distribution
In probability theory and statistics, the Laplace distribution is a continuous probability distribution named after Pierre-Simon Laplace. It is also sometimes called the double exponential distribution, because it can be thought of as two exponen ...
, a bilateral exponential distribution
**
Gumbel distribution, an iterated exponential distribution
* Double exponential integration, most commonly
tanh-sinh quadrature
*
Double exponential smoothing
