  2. Computational complexity theory - Wikipedia

    en.wikipedia.org/wiki/Computational_complexity...

    The time required by a deterministic Turing machine on input is the total number of state transitions, or steps, the machine makes before it halts and outputs the answer ("yes" or "no"). A Turing machine M {\displaystyle M} is said to operate within time f ( n ) {\displaystyle f(n)} if the time required by M {\displaystyle M} on each input of ...

  3. Time complexity - Wikipedia

    en.wikipedia.org/wiki/Time_complexity

    Graphs of functions commonly used in the analysis of algorithms, showing the number of operations N as the result of input size n for each function. 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 ...

  4. Time - Wikipedia

    en.wikipedia.org/wiki/Time

    Time is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. [1] [2] [3] It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the ...

  5. Discrete time and continuous time - Wikipedia

    en.wikipedia.org/wiki/Discrete_time_and...

    Discrete time views values of variables as occurring at distinct, separate "points in time", or equivalently as being unchanged throughout each non-zero region of time ("time period")—that is, time is viewed as a discrete variable. Thus a non-time variable jumps from one value to another as time moves from one time period to the next.

  6. Blocking (statistics) - Wikipedia

    en.wikipedia.org/wiki/Blocking_(statistics)

    One useful way to look at a randomized block experiment is to consider it as a collection of completely randomized experiments, each run within one of the blocks of the total experiment. [ 3 ] Randomized block designs (RBD)

  7. Running total - Wikipedia

    en.wikipedia.org/wiki/Running_total

    A running total or rolling total is the summation of a sequence of numbers which is updated each time a new number is added to the sequence, by adding the value of the new number to the previous running total. Another term for it is partial sum. The purposes of a running total are twofold.

  9. Mean sojourn time - Wikipedia

    en.wikipedia.org/wiki/Mean_sojourn_time

    Consider a system S in the form of a closed domain of finite volume in the Euclidean space.Further, consider the situation where there is a stream of ”equivalent” particles into S (number of particles per time unit) where each particle retains its identity while being in S and eventually – after a finite time – leaves the system irreversibly (i.e., for these particles the system is ...
