Fixed-point combinators are often used in the "anonymous" form of this method.
Fixed-point combinators are often used in the "anonymous" form of this method. Semidecideable sets are enumerable through this method. In Scheme, a trampoline is often used to implement the "tail" type of this method without growing the stack. A total computable function that lacks the primitive form of this property is named for Ackermann. Often used to define the Catalan numbers and the factorial function, programming languages such as Java and Ruby use iteration instead of this to avoid stack overflows. For 10 points, name this concept used in computer science to write algorithms such as merge sort, in which a function being defined is applied in its definition.
