Recursion, in mathematics and computer science, is a method of defining functions in which the function being defined is applied within its own definition; specifically it is defining an infinite statement using finite components. The term is also used more generally to describe a process of repeating objects in a self-similar way. For instance, when the surfaces of two mirrors are exactly parallel with each other the nested images that occur are a form of infinite recursion.
In mathematics and computer science, a class of objects or methods exhibit recursive behavior when they can be defined by two properties:
For example, the following is a recursive definition of a person’s ancestors:
The Fibonacci sequence is a classic example of recursion:
A convenient mental model of recursion defines the recursive object (whether that object is an equation, an algorithm, an image, or a rule) in terms of “previously defined” objects of the same class. For example: How do you move a stack of 100 boxes?
