Comparison of two revisions of an example file, based on their longest common subsequence (black) A longest common subsequence (LCS) is the longest subsequence common to all sequences in a set of sequences (often just two sequences).
In this variant of the problem, which allows for interesting applications in several contexts, it is possible to devise an optimal selection procedure that, given a random sample of size as input, will generate an increasing sequence with maximal expected length of size approximately . [11] The length of the increasing subsequence selected by ...

In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
Let μ be the smallest index such that the value x μ reappears infinitely often within the sequence of values x i, and let λ (the loop length) be the smallest positive integer such that x μ = x λ + μ. The cycle detection problem is the task of finding λ and μ. [1]
If x = m, add it to the set of c copies of m (and increment c). If x ≠ m and c > 0, then remove one of the c copies of m from the left-over set and pair it with the final value (and decrement c). If c = 0, then set m ← x and add x to the (previously empty) set of copies of m (and set c to 1). In all cases, the loop invariant is maintained. [1]
To find a maximum clique, one can systematically inspect all subsets, but this sort of brute-force search is too time-consuming to be practical for networks comprising more than a few dozen vertices. Although no polynomial time algorithm is known for this problem, more efficient algorithms than the brute-force search are known.
In the C programming language, Duff's device is a way of manually implementing loop unrolling by interleaving two syntactic constructs of C: the do-while loop and a switch statement. Its discovery is credited to Tom Duff in November 1983, when Duff was working for Lucasfilm and used it to speed up a real-time animation program.
