  2. Index of coincidence - Wikipedia

    en.wikipedia.org/wiki/Index_of_coincidence

    This count, either as a ratio of the total or normalized by dividing by the expected count for a random source model, is known as the index of coincidence, or IC or IOC [2] or IoC [3] for short. Because letters in a natural language are not distributed evenly , the IC is higher for such texts than it would be for uniformly random text strings.

  3. Inversion of control - Wikipedia

    en.wikipedia.org/wiki/Inversion_of_control

    (Dependency injection is an example of the separate, specific idea of "inverting control over the implementations of dependencies" popularised by Java frameworks.) [4] Inversion of control is sometimes referred to as the "Hollywood Principle: Don't call us, we'll call you".

  4. IBM Open Class - Wikipedia

    en.wikipedia.org/wiki/IBM_Open_Class

    C Set++ v2.01 for OS/2, the first release of IOC/OCL/IUICL. IBM Open Class (IOC) is an IBM C++ product originally developed by Kevin Leong and originally known under several names in the C++ industry, including ICL (IBM Class Library), UICL (User Interface Class Library), and OCL (Open Class Library).

  5. Power system protection - Wikipedia

    en.wikipedia.org/wiki/Power_system_protection

    There are two types of overload protection: instantaneous overcurrent (IOC) and time overcurrent (TOC). Instantaneous overcurrent requires that the current exceeds a predetermined level for the circuit breaker to operate. Time overcurrent protection operates based on a current vs time curve.

  6. Granularity (parallel computing) - Wikipedia

    en.wikipedia.org/wiki/Granularity_(parallel...

    The goal should be to maximize parallelization (split work into enough units to evenly distribute it across most available processors) while minimizing communication overhead (ratio of time spend on communication vs time spend on computation). In our example, if the number of pictures to process is high compared to the number of workers, it ...

  7. Time complexity - Wikipedia

    en.wikipedia.org/wiki/Time_complexity

    For example, a procedure that adds up all elements of a list requires time proportional to the length of the list, if the adding time is constant, or, at least, bounded by a constant. Linear time is the best possible time complexity in situations where the algorithm has to sequentially read its entire input.

  8. Loop dependence analysis - Wikipedia

    en.wikipedia.org/wiki/Loop_dependence_analysis

    This is an anti dependence because variable b is first read in statement S1 and then variable b is written to in statement S2. This can be represented by S1 →A S2. An anti dependence can be seen by different iterations in a loop. The following example shows an example of this case:

  9. Gather/scatter (vector addressing) - Wikipedia

    en.wikipedia.org/wiki/Gather/scatter_(vector...

    Gather/scatter is a type of memory addressing that at once collects (gathers) from, or stores (scatters) data to, multiple, arbitrary memory indices. Examples of its use include sparse linear algebra operations, [1] sorting algorithms, fast Fourier transforms, [2] and some computational graph theory problems. [3]
