Algorithm

An algorithm is a finite series of well-defined instructions that is often used to solve a class of specialised problems or to execute a calculation in mathematics and computer science. Algorithms are used to specify how computations and data processing will be carried out and stored. Machine learning algorithms may make automatic deductions (also known as automated reasoning) and employ mathematical and logical tests to redirect the code along multiple pathways by using artificial intelligence (referred to as automated decision-making). Alan Turing was the first to use human traits as descriptors of computers in a metaphorical manner, using terminology such as "memory," "search," and "stimulus" to describe machines.

A heuristic, on the other hand, is a problem-solving strategy that is not completely stated and does not guarantee right or optimum solutions, particularly in problem domains where there is no well-defined correct or ideal conclusion, such as in optimization problems.

An algorithm is a technique for computing a function that can be stated in a limited amount of space and time, as well as in a well-defined formal language. It is a method that is efficient. The instructions describe a computation that, when run, continues through a limited number of well-defined subsequent stages, finally creating "output" and terminating at a final ending state. The instructions begin with an initial state and initial input (which may be empty). A predictable movement from one state to another is not always the case; certain algorithms, known as randomised algorithms, include random input into their computations.
