Practical cycle-detection algorithms do not find λ and μ exactly. [1] They usually find lower and upper bounds μ l ≤ μ ≤ μ h for the start of the cycle, and a more detailed search of the range must be performed if the exact value of μ is needed. Also, most algorithms do not guarantee to find λ directly, but may find some multiple kλ ...
Loop unrolling, also known as loop unwinding, is a loop transformation technique that attempts to optimize a program's execution speed at the expense of its binary size, which is an approach known as space–time tradeoff. The transformation can be undertaken manually by the programmer or by an optimizing compiler.
Initialise c = 1 and loop variable e′ = 0; While e′ < e do Increment e′ by 1; Calculate c = (b ⋅ c) mod m; Output c; Note that at the end of every iteration through the loop, the equation c ≡ b e′ (mod m) holds true. The algorithm ends when the loop has been executed e times. At that point c contains the result of b e mod m.

In all cases, the loop invariant is maintained. [1] After the entire sequence has been processed, it follows that no element x ≠ m can have a majority, because x can equal at most one element of each unequal pair and none of the remaining c copies of m. Thus, if there is a majority element, it can only be m. [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.
After loop iteration i, the first i elements of the array contain a random permutation. Each loop iteration maintains this property while increasing i . Alternatively, it can be shown that there are n ! different sequences of random numbers j , and each corresponds with a different permutation.
