  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. 2-satisfiability - Wikipedia

    en.wikipedia.org/wiki/2-satisfiability

    The median of any three solutions is formed by setting each variable to the value it holds in the majority of the three solutions. This median always forms another solution to the instance. [32] Feder (1994) describes an algorithm for efficiently listing all solutions to a given 2-satisfiability instance, and for solving several related ...

  5. 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.

  7. Necklace problem - Wikipedia

    en.wikipedia.org/wiki/Necklace_problem

    Radcliffe and Scott showed that if n is prime, 3 is sufficient, and for any n, 9 times the number of prime factors of n is sufficient. Pebody showed that for any n, 6 is sufficient and, in a followup paper, that for odd n, 4 is sufficient. He conjectured that 4 is again sufficient for even n greater than 10, but this remains unproven.

  8. Closest pair of points problem - Wikipedia

    en.wikipedia.org/wiki/Closest_pair_of_points_problem

    The closest pair of points problem or closest pair problem is a problem of computational geometry: given points in metric space, find a pair of points with the smallest distance between them. The closest pair problem for points in the Euclidean plane [ 1 ] was among the first geometric problems that were treated at the origins of the systematic ...

  9. Subset sum problem - Wikipedia

    en.wikipedia.org/wiki/Subset_sum_problem

    n - the number of input integers. If n is a small fixed number, then an exhaustive search for the solution is practical. L - the precision of the problem, stated as the number of binary place values that it takes to state the problem. If L is a small fixed number, then there are dynamic programming algorithms that can solve it exactly.
