An alternative to using mathematical pseudocode (involving set theory notation or matrix operations) for documentation of algorithms is to use a formal mathematical programming language that is a mix of non-ASCII mathematical notation and program control structures. Then the code can be parsed and interpreted by a machine.
A compare-and-swap operation is an atomic version of the following pseudocode, where * denotes access through a pointer: [1]. function cas(p: pointer to int, old: int, new: int) is if *p ≠ old return false *p ← new return true

This algorithm, an example of bottom-up dynamic programming, is discussed, with variants, in the 1974 article The String-to-string correction problem by Robert A. Wagner and Michael J. Fischer. [ 4 ] This is a straightforward pseudocode implementation for a function LevenshteinDistance that takes two strings, s of length m , and t of length n ...
Simple implementation: Jon Bentley shows a version that is three lines in C-like pseudo-code, and five lines when optimized. [1] Efficient for (quite) small data sets, much like other quadratic (i.e., O(n 2)) sorting algorithms; More efficient in practice than most other simple quadratic algorithms such as selection sort or bubble sort
The pseudo code is different from the original Frazer and McKellar ... In a comparison based sorting algorithm the comparison operation is the most performance ...
The pseudocode below uses a function ccw: ccw > 0 if three points make a counter-clockwise turn, ccw < 0 if clockwise, and ccw = 0 if collinear. (In real applications, if the coordinates are arbitrary real numbers, the function requires exact comparison of floating-point numbers, and one has to beware of numeric singularities for "nearly ...
