  2. Stable roommates problem - Wikipedia

    en.wikipedia.org/wiki/Stable_roommates_problem

    a:(b,c,d), b:(c,a,d), c:(a,b,d), d:(a,b,c) In this ranking, each of A, B, and C is the most preferable person for someone. In any solution, one of A, B, or C must be paired with D and the other two with each other (for example AD and BC), yet for anyone who is partnered with D, another member will have rated them highest, and D's partner will ...

  3. Stable marriage problem - Wikipedia

    en.wikipedia.org/wiki/Stable_marriage_problem

    In a uniformly-random instance of the stable marriage problem with n men and n women, the average number of stable matchings is asymptotically ⁡. [6] In a stable marriage instance chosen to maximize the number of different stable matchings, this number is an exponential function of n. [7]

  4. Langford pairing - Wikipedia

    en.wikipedia.org/wiki/Langford_pairing

    Langford pairings are named after C. Dudley Langford, who posed the problem of constructing them in 1958. Langford's problem is the task of finding Langford pairings for a given value of n. [1] The closely related concept of a Skolem sequence [2] is defined in the same way, but instead permutes the sequence 0, 0, 1, 1, ..., n − 1, n − 1.

    S(n, h, t) := solution to a problem consisting of n disks that are to be moved from rod h to rod t. For n=1 the problem is trivial, namely S(1,h,t) = "move a disk from rod h to rod t" (there is only one disk left). The number of moves required by this solution is 2 n − 1.

  7. Bridge and torch problem - Wikipedia

    en.wikipedia.org/wiki/Bridge_and_torch_problem

    Assume that a solution minimizes the total number of crossings. This gives a total of five crossings - three pair crossings and two solo-crossings. Also, assume we always choose the fastest for the solo-cross. First, we show that if the two slowest persons (C and D) cross separately, they accumulate a total crossing time of 15.

  8. 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 ...

  9. Axiom of pairing - Wikipedia

    en.wikipedia.org/wiki/Axiom_of_pairing

    Given any finite number of objects A 1 through A n, there is a set C whose members are precisely A 1 through A n. This set C is again unique by the axiom of extensionality, and is denoted {A 1,...,A n}. Of course, we can't refer to a finite number of objects rigorously without already having in our hands a (finite) set to which the objects in ...
