Pseudocode typically omits details that are essential for machine implementation of the algorithm, meaning that pseudocode can only be verified by hand. [3] The programming language is augmented with natural language description details, where convenient, or with compact mathematical notation .
Karatsuba's basic step works for any base B and any m, but the recursive algorithm is most efficient when m is equal to n/2, rounded up. In particular, if n is 2 k , for some integer k , and the recursion stops only when n is 1, then the number of single-digit multiplications is 3 k , which is n c where c = log 2 3.
Thus, for example, the XMODEM-CRC extension, an early use of CRCs in software, uses an msbit-first CRC. So far, the pseudocode has avoided specifying the ordering of bits within bytes by describing shifts in the pseudocode as multiplications by and writing explicit conversions from binary to polynomial form. In practice, the CRC is held in a ...
The following pseudocode presents the simulated annealing heuristic as described above. It starts from a state s 0 and continues until a maximum of k max steps have been taken. In the process, the call neighbour( s ) should generate a randomly chosen neighbour of a given state s ; the call random(0, 1) should pick and return a value in the ...
For example, in the for statement in the following pseudocode fragment, when calculating the new value for A(i), except for the first (with i = 2) the reference to A(i - 1) will obtain the new value that had been placed there in the previous step.

At every step multiplying the result from the previous iteration, c, by b and performing a modulo operation on the resulting product, thereby keeping the resulting c a small integer. The example b = 4, e = 13, and m = 497 is presented again. The algorithm performs the iteration thirteen times:
The pseudocode below recursively computes the prime implicants given the list of minterms of a boolean function. It does this by trying to merge all possible minterms and filtering out minterms that have been merged until no more merges of the minterms can be performed and hence, the prime implicants of the function have been found.
