  2. Cartesian product - Wikipedia

    en.wikipedia.org/wiki/Cartesian_product

    A table can be created by taking the Cartesian product of a set of rows and a set of columns. If the Cartesian product rows × columns is taken, the cells of the table contain ordered pairs of the form (row value, column value). [4] One can similarly define the Cartesian product of n sets, also known as an n-fold Cartesian product, which can be ...

  3. Multiway number partitioning - Wikipedia

    en.wikipedia.org/wiki/Multiway_number_partitioning

    There is an optimal partition in which all subsets sums are strictly betweel L/2 and 2L (L/2 < C i < 2L for all i in 1,...,k). Particularly, the partition minimizing the sum of squares C i 2, among all optimal partitions, satisfies these inequalities. The PTAS uses an input rounding technique.

  4. Bell polynomials - Wikipedia

    en.wikipedia.org/wiki/Bell_polynomials

    In general, if the integer n is partitioned into a sum in which "1" appears j 1 times, "2" appears j 2 times, and so on, then the number of partitions of a set of size n that collapse to that partition of the integer n when the members of the set become indistinguishable is the corresponding coefficient in the polynomial.

  5. Partition function (number theory) - Wikipedia

    en.wikipedia.org/wiki/Partition_function_(number...

    The values (), …, of the partition function (1, 2, 3, 5, 7, 11, 15, and 22) can be determined by counting the Young diagrams for the partitions of the numbers from 1 to 8. In number theory, the partition function p(n) represents the number of possible partitions of a non-negative integer n.

  6. Largest differencing method - Wikipedia

    en.wikipedia.org/wiki/Largest_differencing_method

    In computer science, the largest differencing method is an algorithm for solving the partition problem and the multiway number partitioning. It is also called the Karmarkar–Karp algorithm after its inventors, Narendra Karmarkar and Richard M. Karp . [ 1 ]

  7. Partition problem - Wikipedia

    en.wikipedia.org/wiki/Partition_problem

    An instance of SubsetSum consists of a set S of positive integers and a target sum T; the goal is to decide if there is a subset of S with sum exactly T. Given such an instance, construct an instance of Partition in which the input set contains the original set plus two elements: z 1 and z 2, with z 1 = sum(S) and z 2 = 2T.

  9. Partition of a set - Wikipedia

    en.wikipedia.org/wiki/Partition_of_a_set

    Partitions of a 4-element set ordered by refinement. A partition α of a set X is a refinement of a partition ρ of X—and we say that α is finer than ρ and that ρ is coarser than α—if every element of α is a subset of some element of ρ. Informally, this means that α is a further fragmentation of ρ. In that case, it is written that ...
