2. Recursion - Wikipedia

   en.wikipedia.org/wiki/Recursion

   A recursive step — a set of rules that reduces all successive cases toward the base case. For example, the following is a recursive definition of a person's ancestor. One's ancestor is either: One's parent (base case), or; One's parent's ancestor (recursive step). The Fibonacci sequence is another classic example of recursion: Fib(0) = 0 as ...

3. Recursion (computer science) - Wikipedia

   en.wikipedia.org/wiki/Recursion_(computer_science)

   Recursion (computer science) Tree created using the Logo programming language and relying heavily on recursion. Each branch can be seen as a smaller version of a tree. Recursive drawing of a Sierpiński Triangle through turtle graphics. In computer science, recursion is a method of solving a computational problem where the solution depends on ...

4. Computability theory - Wikipedia

   en.wikipedia.org/wiki/Computability_theory

   Computability theory. Computability theory, also known as recursion theory, is a branch of mathematical logic, computer science, and the theory of computation that originated in the 1930s with the study of computable functions and Turing degrees. The field has since expanded to include the study of generalized computability and definability.

5. Recurrence relation - Wikipedia

   en.wikipedia.org/wiki/Recurrence_relation

   Definition. A recurrence relation is an equation that expresses each element of a sequence as a function of the preceding ones. More precisely, in the case where only the immediately preceding element is involved, a recurrence relation has the form. where. is a function, where X is a set to which the elements of a sequence must belong.

6. General recursive function - Wikipedia

   en.wikipedia.org/wiki/General_recursive_function

   General recursive function. In mathematical logic and computer science, a general recursive function, partial recursive function, or μ-recursive function is a partial function from natural numbers to natural numbers that is "computable" in an intuitive sense – as well as in a formal one. If the function is total, it is also called a total ...

7. Linear recurrence with constant coefficients - Wikipedia

   en.wikipedia.org/wiki/Linear_recurrence_with...

   A linear recurrence with constant coefficients is an equation of the following form, written in terms of parameters a1, ..., an and b : or equivalently as. The positive integer is called the order of the recurrence and denotes the longest time lag between iterates. The equation is called homogeneous if b = 0 and nonhomogeneous if b ≠ 0 .

8. Divide-and-conquer algorithm - Wikipedia

   en.wikipedia.org/wiki/Divide-and-conquer_algorithm

   In computer science, divide and conquer is an algorithm design paradigm. A divide-and-conquer algorithm recursively breaks down a problem into two or more sub-problems of the same or related type, until these become simple enough to be solved directly. The solutions to the sub-problems are then combined to give a solution to the original problem.

9. Mandelbrot set - Wikipedia

   en.wikipedia.org/wiki/Mandelbrot_set

   The Mandelbrot set within a continuously colored environment. The Mandelbrot set ( / ˈmændəlbroʊt, - brɒt /) [1] [2] is a two-dimensional set with a relatively simple definition that exhibits great complexity, especially as it is magnified. It is popular for its aesthetic appeal and fractal structures. The set is defined in the complex ...
