  2. Anytime algorithm - Wikipedia

    en.wikipedia.org/wiki/Anytime_algorithm

    Anytime algorithms are designed so that it can be told to stop at any time and would return the best result it has found so far. [3] This is why it is called an interruptible algorithm. Certain anytime algorithms also maintain the last result, so that if they are given more time, they can continue from where they left off to obtain an even ...

  3. Interval scheduling - Wikipedia

    en.wikipedia.org/wiki/Interval_scheduling

    Interval scheduling is a class of problems in computer science, particularly in the area of algorithm design. The problems consider a set of tasks. Each task is represented by an interval describing the time in which it needs to be processed by some machine (or, equivalently, scheduled on some resource).

  4. Busy waiting - Wikipedia

    en.wikipedia.org/wiki/Busy_waiting

    Busy-waiting itself can be made much less wasteful by using a delay function (e.g., sleep()) found in most operating systems. This puts a thread to sleep for a specified time, during which the thread will waste no CPU time. If the loop is checking something simple then it will spend most of its time asleep and will waste very little CPU time.

  5. Longest-processing-time-first scheduling - Wikipedia

    en.wikipedia.org/wiki/Longest-processing-time...

    The running time of LPT is dominated by the sorting, which takes O(n log n) time, where n is the number of inputs. LPT is monotone in the sense that, if one of the input numbers increases, the objective function (the largest sum or the smallest sum of a subset in the output) weakly increases. [2] This is in contrast to Multifit algorithm.

  6. Callback (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Callback_(computer...

    In computer programming, a callback is a function that is stored as data (a reference) and designed to be called by another function – often back to the original abstraction layer. A function that accepts a callback parameter may be designed to call back before returning to its caller which is known as synchronous or blocking.

  7. Heterogeneous earliest finish time - Wikipedia

    en.wikipedia.org/wiki/Heterogeneous_Earliest...

    The task with the highest priority for which all dependent tasks have finished is scheduled on the worker which will result in the earliest finish time of that task. This finish time depends on the communication time to send all necessary inputs to the worker, the computation time of the task on the worker, and the time when that processor ...

  8. Exponential backoff - Wikipedia

    en.wikipedia.org/wiki/Exponential_backoff

    The time delay is usually measured in slots, which are fixed-length periods (or slices) of time on the network. In a binary exponential backoff algorithm (i.e. one where b = 2), after c collisions, each retransmission is delayed by a random number of slot times between 0 and 2 c − 1. After the first collision, each sender will wait 0 or 1 ...

  9. Activity selection problem - Wikipedia

    en.wikipedia.org/wiki/Activity_selection_problem

    The activity selection problem is a combinatorial optimization problem concerning the selection of non-conflicting activities to perform within a given time frame, given a set of activities each marked by a start time (s i) and finish time (f i).
