197:. This helps to simplify the core functionality of a potentially confusing method. It can also be used to allow for a small function within a larger program to operate without full functionality temporarily. This method of programming is easier than writing a complete function, as these skeleton functions do not have to include main functionalities and can instead be hardcoded to use during development. They usually involve syntactically correct code to introduce the method, as well as comments to indicate the operation of the program. This is not always necessary to call a piece of text skeleton code.
490:âPipesâ are the more traditional forms of algorithms, where each method or function is run in a sequence. This follows the order in which the programmer has written their code. This is made parallel by computing varied tasks on a set of data, typically input, simultaneously to improve performance and speed. Each simultaneous computation is known as a stage. The pipe algorithm can be nested, where one is within another, each splitting up responsibilities to increase speed and also the number of stages.
284:, focuses heavily on a structured documentation page with completely separated methods for each object part of Java's packages. Object oriented languages focus on a hierarchy based structure to their implementations, rather than a simple top-down approach found in other languages. âObjectsâ store data and variables in them, allowing for a typically more efficient program to be written. These objects have individual functions that can access internal variables, known as methods.
224:. It is a plain English portrayal of a particular function within a larger system, or can even be a representation of a whole program. Pseudocode is similar to skeleton programming, however deviates in the fact that pseudocode is primarily an informal method of programming. Dummy code is also very similar to this, where code is used simply as a placeholder, or to signify the intended existence of a method in a class or interface.

517:âDivide and conquerâ uses a map skeleton as its basis, combining this with a while skeleton to solve the problem. In map algorithms, functions on data are applied simultaneously. In âdivide and conquerâ the set of data provided has a function applied to it using the map skeleton, however this can be applied recursively using the âwhileâ algorithm. The âwhileâ is only broken when the entire problem is solved.
234:. A typical programmer is so conditioned with the idea of writing simplified code in some manner, be it by writing pseudocode or skeleton code, or even just by drawing a diagram, that this has a measurable impact on how well they can write their final implementation. This has been found over a number of applications, with different programmers working in different languages and varied
503:âWhileâ is an algorithm very similar to the operation of a âforâ algorithm, where a task is completed a number of times. However, in âwhileâ algorithms, the program computes the task a number of times before a conditional statement is met. This means that the âwhileâ algorithm can perform its task a different number of times for each time it is run.
487:âFarmsâ are known as a group of tasks, a worker, or as a master or slave of another function. It completes the given tasks by replicating the tasks over multiple threads and running these concurrently. This divides the load for a specific thread, effectively creating a master / slave relationship between the threads.

Other forms of NLIs use different forms of input, ranging from other users speaking different languages, to gesture based input to produce a very similar result. With programming languages being developed and written primarily in
English, people speaking other languages find it hard to develop new
520:âBranch and boundâ is an algorithm that also uses map algorithms, however instead of applying the âwhileâ algorithm to run the tasks simultaneously, this algorithm splits the tasks into branches. Each branch has a specific purpose, or âboundâ, where the conditional statement will cause it to stop.
512:
These skeletons are very different to the typical skeletons found above. âResolutionâ algorithms use a combination of methods to solve a specified problem. The algorithm's given problem can be a âfamily of problemsâ. There are two main types of these skeletons, âdivide and conquerâ or âbrand and

460:âMapsâ are the most commonly used data parallel algorithms, and typically involve a single operation completed on a large set of data. To increase efficiency, a number of data sets have this operation applied to them simultaneously, before the data is structured together again at the end.

These operations, as their name suggests, work on tasks. Each type of algorithm under this is different due to a change in the behaviour between tasks. Task parallel algorithms include âsequentialsâ, âfarmsâ, âpipesâ, âifâ, âforâ and âwhileâ.

These skeleton algorithms are used to develop programs that work on large data based software, usually identifying the connections between data for later use. Data parallel algorithms include âmapsâ, âforksâ and âreducesâ or âscansâ.

This method of program design is also most often done on pen and paper, further moving the text from what is actually to be implemented. Skeleton programming mimics this, but differs in the way that it is commonly written in an
