The pseudocode-like language PlusCal was created in 2009; it transpiles to TLA + and is useful for specifying sequential algorithms. TLA +2 was announced in 2014, expanding language support for proof constructs.
In object-oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact classes. Rather than by calling a constructor , this is accomplished by invoking a factory method to create an object.
This method contains code for the parts of the overall algorithm that are invariant. The template ensures that the overarching algorithm is always followed. [1] In the template method, portions of the algorithm that may vary are implemented by sending self messages that request the execution of additional helper methods. In the base class ...
There are several broadly recognized algorithmic techniques that offer a proven method or process for designing and constructing algorithms. Different techniques may be used depending on the objective, which may include searching, sorting, mathematical optimization, constraint satisfaction, categorization, analysis, and prediction.
In addition, we can also specify the behaviour of a type-indexed values for a specific constructor using constructor cases, and reuse one generic definition in another using default cases. The resulting type-indexed value can be specialized to any type. Kind-indexed types are types indexed over kinds, defined by giving a case for both * and k ...
In these languages, data and methods to manipulate the data are in the same code unit called an object. This encapsulation ensures that the only way that an object can access data is via methods of the object that contains the data. Thus, an object's inner workings may be changed without affecting code that uses the object.
For examples of this specification-method applied to the addition algorithm "m+n" see Algorithm examples. Sipser begins by defining '"algorithm" as follows: "Informally speaking, an algorithm is a collection of simple instructions for carrying out some task.
JaSkel [30] is a Java-based skeleton framework providing skeletons such as farm, pipe and heartbeat. Skeletons are specialized using inheritance. Programmers implement the abstract methods for each skeleton to provide their application specific code. Skeletons in JaSkel are provided in both sequential, concurrent and dynamic versions.
