Parsons problems consist of a partially completed solution and a selection of lines of code that some of which, when arranged appropriately, correctly complete the solution. There is great flexibility in how Parsons problems can be designed, including the types of code fragments from which to select, and how much structure of the solution is ...
Function calls and blocks of code, such as code contained within a loop, are often replaced by a one-line natural language sentence. Depending on the writer, pseudocode may therefore vary widely in style, from a near-exact imitation of a real programming language at one extreme, to a description approaching formatted prose at the other.
The pseudocode DPLL function only returns whether the final assignment satisfies the formula or not. In a real implementation, the partial satisfying assignment typically is also returned on success; this can be derived by keeping track of branching literals and of the literal assignments made during unit propagation and pure literal elimination.
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 ...
The algorithm in pseudocode is as follows: let the input be a string I consisting of n characters: a 1... a n. let the grammar contain r nonterminal symbols R 1... R r, with start symbol R 1. let P[n,n,r] be an array of booleans. Initialize all elements of P to false. let back[n,n,r] be an array of lists of backpointing triples.
The preprocessing phase, in pseudocode, is as follows (for an alphabet of 256 symbols, i.e., bytes): // Unlike the original, we use zero-based indices here. function preprocess ( pattern ) T := new table of 256 integers for i from 0 to 256 exclusive T [ i ] := length ( pattern ) for i from 0 to length ( pattern ) - 1 exclusive T [ pattern [ i ...

This leads to the following pseudocode, where the added or changed code is highlighted: Input #1 : n > 2, an odd integer to be tested for primality Input #2 : k , the number of rounds of testing to perform Output : (“ multiple of ”, m ) if a nontrivial factor m of n is found, “ composite ” if n is otherwise found to be composite ...
