  2. Smallest-circle problem - Wikipedia

    en.wikipedia.org/wiki/Smallest-circle_problem

    The solution of the subproblem is either the solution of the unconstrained problem or it is used to determine the half-plane where the unconstrained solution center is located. The n 16 {\textstyle {\frac {n}{16}}} points to be discarded are found as follows: The points P i are arranged into pairs which defines n 2 {\textstyle {\frac {n}{2 ...

  3. Unit testing - Wikipedia

    en.wikipedia.org/wiki/Unit_testing

    Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement [definition needed].While it may imply that it is a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it does not mean functions/methods, modules or classes always correspond to units.

  4. Packing problems - Wikipedia

    en.wikipedia.org/wiki/Packing_problems

    Packing circles in a circle - closely related to spreading points in a unit circle with the objective of finding the greatest minimal separation, d n, between points. Optimal solutions have been proven for n ≤ 13, and n = 19. Packing circles in a square - closely related to spreading points in a unit square with the objective of finding the ...

  5. Monty Hall problem - Wikipedia

    en.wikipedia.org/wiki/Monty_Hall_problem

    If the car is behind door 1, the host can open either door 2 or door 3, so the probability that the car is behind door 1 and the host opens door 3 is ⁠ 1 / 3 ⁠ × ⁠ 1 / 2 ⁠ = ⁠ 1 / 6 ⁠. If the car is behind door 2 – with the player having picked door 1 – the host must open door 3, such the probability that the car is behind door ...

  6. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    This is the smallest value for which we care about observing a difference. Now, for (1) to reject H 0 with a probability of at least 1 − β when H a is true (i.e. a power of 1 − β), and (2) reject H 0 with probability α when H 0 is true, the following is necessary: If z α is the upper α percentage point of the standard normal ...

  7. Test-driven development - Wikipedia

    en.wikipedia.org/wiki/Test-driven_development

    Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.

  9. Weighted sum model - Wikipedia

    en.wikipedia.org/wiki/Weighted_Sum_Model

    For instance, the relative weight of the first criterion is equal to 0.20, the relative weight for the second criterion is 0.15 and so on. Similarly, the value of the first alternative (i.e., A 1) in terms of the first criterion is equal to 25, the value of the same alternative in terms of the second criterion is equal to 20 and so on.
