  2. Mutual recursion - Wikipedia

    en.wikipedia.org/wiki/Mutual_recursion

    As a more general class of examples, an algorithm on a tree can be decomposed into its behavior on a value and its behavior on children, and can be split up into two mutually recursive functions, one specifying the behavior on a tree, calling the forest function for the forest of children, and one specifying the behavior on a forest, calling ...

  3. Disjoint sets - Wikipedia

    en.wikipedia.org/wiki/Disjoint_sets

    Disjoint-set data structures [9] and partition refinement [10] are two techniques in computer science for efficiently maintaining partitions of a set subject to, respectively, union operations that merge two sets or refinement operations that split one set into two. A disjoint union may mean one of two things. Most simply, it may mean the union ...

  4. R-tree - Wikipedia

    en.wikipedia.org/wiki/R-tree

    In quadratic split, the algorithm searches for the pair of rectangles that is the worst combination to have in the same node, and puts them as initial objects into the two new groups. It then searches for the entry which has the strongest preference for one of the groups (in terms of area increase) and assigns the object to this group until all ...

    en.wikipedia.org/wiki/List_of_Java_keywords

    By default, the value of boolean primitive type is false. This keyword is also used to declare that a method returns a value of the primitive type boolean. break Used to end the execution in the current loop body. Used to break out of a switch block. byte The byte keyword is used to declare a field that can hold an 8-bit signed two's complement ...

  6. Partition refinement - Wikipedia

    en.wikipedia.org/wiki/Partition_refinement

    When a set S i that has already been chosen is split by a refinement, only one of the two resulting sets (the smaller of the two) needs to be chosen again; in this way, each state participates in the sets X for O(s log n) refinement steps and the overall algorithm takes time O(ns log n), where n is the number of initial states and s is the size ...

  8. Subset sum problem - Wikipedia

    en.wikipedia.org/wiki/Subset_sum_problem

    Let A be the sum of the negative values and B the sum of the positive values; the number of different possible sums is at most B-A, so the total runtime is in (()). For example, if all input values are positive and bounded by some constant C , then B is at most N C , so the time required is O ( N 2 C ) {\displaystyle O(N^{2}C)} .

    Separate the stalk into individual ribs, and cut or use as directed. For a single celery rib: Just as with the larger bunch, rinse the rib under cool water to remove dirt and debris.
