If the data is stored on a magnetic tape where seek time depends on the current head position, a tradeoff between longer seek time and more comparisons may lead to a search algorithm that is skewed similarly to Fibonacci search. Fibonacci search is derived from Golden section search, an algorithm by Jack Kiefer (1953) to search for the maximum ...
An important application of divide and conquer is in optimization, [example needed] where if the search space is reduced ("pruned") by a constant factor at each step, the overall algorithm has the same asymptotic complexity as the pruning step, with the constant depending on the pruning factor (by summing the geometric series); this is known as ...
The original motivation for fibonacci search, as given by Ferguson in his 1960 article, was that a “machine having no binary shift requires a division” to find the next array index in a binary search, while in fibonacci search, “successive increments are found by subtraction”.

Binary search is usually one of the first algorithms taught to computer science students. The premise is quite simple: given a sorted list of numbers, binary search eliminates halves of the list in which the number you are looking for cannot lie until it finds the number. However, binary search has lots of subtleties.
Abstractly, a dichotomic search can be viewed as following edges of an implicit binary tree structure until it reaches a leaf (a goal or final state). This creates a theoretical tradeoff between the number of possible states and the running time: given k comparisons, the algorithm can only reach O(2 k ) possible states and/or possible goals.

A Lagged Fibonacci generator (LFG or sometimes LFib) is an example of a pseudorandom number generator. This class of random number generator is aimed at being an improvement on the 'standard' linear congruential generator. These are based on a generalisation of the Fibonacci sequence. The Fibonacci sequence may be described by the recurrence ...
