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]
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.
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.
LOOP is a simple register language that precisely captures the primitive recursive functions. [1] The language is derived from the counter-machine model . Like the counter machines the LOOP language comprises a set of one or more unbounded registers , each of which can hold a single non-negative integer.
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 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 ...
A similar loop appears in computations of the hailstone sequence. A bit array can be used to implement a priority queue. In this context, find first set (ffs) is useful in implementing the "pop" or "pull highest priority element" operation efficiently. The Linux kernel real-time scheduler internally uses sched_find_first_bit() for this purpose ...
