  2. Hash table - Wikipedia

    en.wikipedia.org/wiki/Hash_table

    Cuckoo hashing is a form of open addressing collision resolution technique which guarantees () worst-case lookup complexity and constant amortized time for insertions. The collision is resolved through maintaining two hash tables, each having its own hashing function, and collided slot gets replaced with the given item, and the preoccupied ...

  3. Cuckoo hashing - Wikipedia

    en.wikipedia.org/wiki/Cuckoo_hashing

    Cuckoo hashing is a form of open addressing in which each non-empty cell of a hash table contains a key or key–value pair.A hash function is used to determine the location for each key, and its presence in the table (or the value associated with it) can be found by examining that cell of the table.

  4. Worst-case complexity - Wikipedia

    en.wikipedia.org/wiki/Worst-case_complexity

    The order of growth (e.g. linear, logarithmic) of the worst-case complexity is commonly used to compare the efficiency of two algorithms. The worst-case complexity of an algorithm should be contrasted with its average-case complexity, which is an average measure of the amount of resources the algorithm uses on a random input.

  5. Best, worst and average case - Wikipedia

    en.wikipedia.org/wiki/Best,_worst_and_average_case

    But given a worst-case input, its performance degrades to O(n 2). Also, when implemented with the "shortest first" policy, the worst-case space complexity is instead bounded by O(log(n)). Heapsort has O(n) time when all elements are the same. Heapify takes O(n) time and then removing elements from the heap is O(1) time for each of the n elements.

  6. Hash function - Wikipedia

    en.wikipedia.org/wiki/Hash_function

    The practical worst case is the expected longest probe sequence (hash function + collision resolution method). This analysis considers uniform hashing, that is, any key will map to any particular slot with probability 1/ m , a characteristic of universal hash functions.

    In one case, money laundering networks deposited funds in the U.S. and quickly withdrew them using ATMs in Colombia, ultimately laundering millions, the U.S. Justice department said in October.

  8. Perfect hash function - Wikipedia

    en.wikipedia.org/wiki/Perfect_hash_function

    Perfect hash functions may be used to implement a lookup table with constant worst-case access time. A perfect hash function can, as any hash function, be used to implement hash tables, with the advantage that no collision resolution has to be implemented. In addition, if the keys are not in the data and if it is known that queried keys will be ...

    The Panthers, now in their sixth season, haven’t given fans much reason to celebrate. In the 2013 and 2014 seasons, competing at the highest level of the National Collegiate Athletic Association, the team recorded just a single victory. Average attendance last year was among the 10 worst in the NCAA’s top level.
